today i was uploading LW, and i think i had 100 some files and they just dissapearded from my library and i cant find them ? pleez help :-(

What you mean is you accidentally deleted them right!?! eeK! You'll need a file recovery utility like norton utilities or else get a free one here: PC Inspector File Recovery (click on link)

no i didnt delete them, my computer was acting up and it froze and then this LW screen pops up and says something about an internal error so i go on about my business and come back and get on and everything is gone, it says that im not sharing ? could i have made it stop sharing ?
