Hi, I very foolishly wound an already wound lens the wrong way, ie counter clockwise instead of leaving it alone, as in this case it was already to be attached to an already wound camera! As I turned the screw on the lens with a screwdriver it met with some resistance but then it locked after releasing the lens shutter.So I could not attach it to my already wound camera.Now the alignment will not stay in the correct position and keeps flicking back to the wrong position.Please help!!

Well I am sorry to have to tell you this but i fear that it maybe far beyond any help? As you have realized one should never ever force delicate things such as this...Once forced and this type of things happen, often it is beyond repair?
To my mind you only have one shot, and that's to take it to a professional and hopefully they maybe able to "Chase" (Repair the threads with special tools) the threads on Both units? However if this cannot be done, then I am afraid you may have to replace it? sorry about that. but it is better to know than not?
