Cannot adjust aperture or shutter speed in manual modes
Have only used my new Canon EOS Rebel DSLR XS a handful of times, and all of a sudden, I cannot adjust the aperture or shutter speed while in any of the manual setting modes (Tv, Av, M). Has anyone else had this problem, and how do I fix?

On right hand top of the camera there is a Mode dial. Move the dial to Av (aperture priority) then rotate the wheel in front of this dial to set the F stop. The shutter speed will automatically adjust by the light meter.
It may just be too dark for action photography. Try turning your ISO up to 1000+. Set your computer in Tv (Time Priority Mode). Use the top wheel to adjust the shutter time to something like 200 or greater. Keep an eye on the aperture value. If it starts flashing, you don't have enough light to support your settings.
You need to understand the relationship and teractivity of aperture, shutter speed and iso. In Av mod, you choose the aperture and the camera makes thw shutter speed agjustment, In Tv mode, you set the shutter speed and the camera makes the aperture adjustment, In manual, you have to set both shutter speed and aperture manually. If the ISO mode is set to AUTO, the camera chooses the sensors sensitivity to light automatically. Change to specific ISO (200-400 for daylight and 799-1600 for night). Take a picture in AV mode and note what shutter speed the camera chose. Then switch to TC mode choose the same shutter speed and see if camera chose the same aperture(f-stop) you chose in first shot. Change to Manual and choose same f-stop and shutter speed the camera chose for you in the other modes. Compare all three photos. They should be almost if not exactly the same exposure wise. In Tv mode choose a dlowers shutter speed, In Manual choose a combo of slower shuuter and wider f-stop(smaller number). Read your manual.
If your camera is a Rebel XS you should have a dial on the top right with a series of letters and icons. To set your camera so you manually control the shutter speed turn this dial too "TV" (Time Value). This setting will allow you to select the shutter speed and the aperture will open or close to achieve the correct exposure. The "M" is (Manual) where you would select both the shutter speed and aperture "AV" is (Aperture Value) where the user selects the aperture they want and the shutter speed increases or decreases to obtain a proper exposure. The "P" (Program) mode allows the camera to automatically select the shutter speed and aperture
Which mode are you on? When you zoom in, the maximum aperture size decreases to f/5.6 in the kit lens. Sometimes it may be too dark or shutter speed too slow so the camera doesn't shoot. If you're in "P" (program) mode, full auto mode or any of the Basic Modes, the aperture/shutter is auto. In other modes (Av, M, etc) you can turn the dial on the top of the camera to adjust shutter speed to a lower number.
First off, welcome to the world of photography! Good luck and have fun!!!
Like any slr, you have the option of Manual exposure. I'm not familiar w/ modern Canons (I use Nikon). According to this page, however, you also have aperture priority and shutter priority. I'm pretty sure ALL modern Canons have bracketing modes as well (Use this for HDR).
I couldn't find the 450 manual (I'm assuming Canon's web devs are behind), but I did find the instruction manual for the 400 :
Should be similar, probably w/o some of the functions. Although you SHOULD have a book w/ your camera ;). Read it thoroughly.
Ok, according to the 400 manual, put your camera into Manual mode, then adjust the regular dial to adjust shutter speed. Then, to adjust aperture, hold in the A/V button while you adjust the same dial.
Like I said, may be a bit different. I think the dial may even be digital buttons rather than analog...
You may try this. Reset all in the menu setup. What you will be doing to to reset all the settings back to factory settings. Then you will want to go through the settings and reset them the way you prefer.
