Both, But start at the rear to remove the electronics and the outer barrels. Remove any rubber grip to expose 'hidden screws'. I would mark everything or document with pictures during disassembly.

You probably have to set the aperture manually on the lens, because it
might not have CPU contacts. I think changing the aperture on the
camera will probably have no effect, so just try twisting the aperture
ring to wide open.
You usually have to set the aperture at the minimum setting (highest number) so that if the camera is choosing the aperture, it can stop down to the required value.
No good having it set at f2.8 if the shot needs f11.
If the lens is very old, it might have a manual iris that you have to set yourself on the lens. The lenses that stop down automatically will have a tiny peg on the mount that a suitable camera can operate. Gentle pushing of this peg while looking through the lens will tell if it is stopping down - set it wide open first.
If you have a depth of field preview button, this will also have the same effect with the lens on the camera if the body matches up with the lens.

If it's only two months old then it's still under the manufacturer's warranty so send it back to Tamron. I can't tell you where to send it as you haven't said which country you're in. Tamron value their reputation and usually provide excellent after-sales care.
If you're in the UK you additionally have Sale of Goods Act protection for up to six years in England and Wales and five years in Scotland. Either way, the Act allows you to demand a full refund or replacement from the retailer; I'd suggest a refund as bad lenses often come in batches and a different supplier is less likely to have one from the same production batch.
Note that any attempt to fix the lens other than by normal use of the lens and camera controls may completely remove your warranty benefits or consumer protection.

With an SLR you only get true macro focussing on a lens that has proper macro focussing abilities. Unfortunately in the photogaraphy world, there are a huge number of lenses which claim to have macro ability but are stretching the term far too much.
Strictly speaking, macro means that the lens is capable of producing images on the sensor which are the same size as the actual subject or even bigger, at life size this is described as 1:1 macro. Your Tamron lens is only capable of a maximum 1:3.7 "macro", and that's only at the 200mm zoom setting with the subject no closer than 45cm from the lens. By SLR zoom lens standards, that's actually pretty good, but if you want to go closer and get greater magnification you need to either use a supplementary close-up filter lens or for better optical quality use a set of extension rings. The trade off with close up filter lenses is poor image quality and usually plenty of colour fringing and with extension rings is that if you're using a 2x magnification at 200mm, your f5-ish maximum aperture at 200mm becomes a very dark f10.
The only way to get good macro results is to either use a proper (=expensive) macro lens and excellent lighting, or use extension rings plus a good ring flash unit. However you can improve your macro by investing in a more capable zoom lens with a closer minimum focus distance and a better aperture at the telephoto end of the range. This can be expensive, or you can pick up some very cheap 35mm film SLR lenses. Using an adapter will never allow you to achieve infinity focus on a Canon digital SLR but you can get a close focussing 200mm f3.8 very cheaply. The crop factor of your smaller sensor means it will have the same angle of view as a 310mm lens but the aperture will remain at f3.8. As Canon digital SLR's have the deepest body register (lens to sensor distance) of the current systems then you'll also have the effect of using it on an extension ring. The downside is that you'll have to use the lens in a totally manual mode as no information will be communicated to your camera body. By mounting the lens back to front using a reversing ring you can achieve some really stunning macro magnifications but then you need a tripod, powerful flash and absolutely no wind... There was also a Makinon 80-200mm zoom which sells for next to nothing on auction websites, but it had a macro collar which allowed it to achieve around half size macro (1:2).
Alternatively, if the Fuji still works and does the job just keep it in your camera bag ready for those types of shots. overall, that seems the easiest and best solution unless you really want to get heavily into macro shooting.
I hope that I've helped you, please ask more if there's anything unclear. I've tried to keep a very complicated subject as simple as possible. Please also take a moment to rate my answer.

Hello. Yes it can be repaired. Take it into your local Nikon shop for a free estimate, it is often the case that all these lenses need is an internal cleaning and lube and then they are good to go again.
4 thumbs up please. ty
