you dont have to frikin reinstall windows, or get the actuall .dll file anywhere! thats not the problem. This mostly happens with ppl still running win98. All you need is to dl the limewire larger back up. This really is the fix for just about everything....read ppl...if this doesnt fix ur problem, then ur lying cuz its %100 fulproof for this problem.

ps. reinstalling windows shouldn't fix this, but if it does let me know!
