Vista blue screen crashes cause Limewire to reset...

[vsjane]

Running Vista Home Premium on a HP notebook and encounter quite a lot of blue screen crashes, especially while downloading from Limewire. Recently, this nuisance has begun to include Limewire's resetting itself, as though I had just purchased it. Each time, all files are lost! Each time, changes are made that make no sense - how files are saved and where. Would love to hear any answer to this annoying problem. Thanks, Jane
