I had one other weird problem with my computer. It could not find one of the USB drivers for my new video camera. The driver was one that is included in windows xp. I built the thing about 2 months ago with wxp pro. I decided to blow it out and reinstall everything including system board driver which I am sure I did before. Bottom line, after reinstalling java and lime wire (same versions that were not working) now work... Including my USB drivers for the camcorder... Good luck to those still having problems.
