Fuji-2300 FinePix Camera

Hello

I have this problem with a FinePix 2300 camera and WinXP. Let me explain what happened. Well, a friend of mine purchased a new PC with WinXP Home Edition on as well as a Fuji 2300 finepix camera and installed the drivers from the supplied driver disk and this installed the incorrect drivers for the camera, namely the MX Series (which uses Serial) and now I cannot delete it. WinXP detects the correct driver, but when trying to download the images from the camera it gives the error "Already in Use", because the two drivers are clashing.

The only I can think of removing it is to use Regedit, but what do I look for and which keys do I delete?

Any help would be appreciated.

Thanx
