Heya GEMMA, this is a Ubuntu Linux oriented forum, so requesting help for a WinXP problem is a little odd--but perhaps not totally out of line, since I bet the folks around here know more about windows than the average posters on a Windows forum. LOL. I do hope you sort your problem.
I've the same camera, and though it works great and shows up nicely on the desktop when plugged in with Ubuntu, I've not tried it as a webcam on Linux.
Good luck.
