You sure aren't giving a lot of info Katie. Do you have space ? Have you tried defragmenting harddisk ? Did you make any changes to your system before the problem occured (maybe upgrading limewire) or setting up user accounts. Did Limewire work for a long time before this happened ? Are you using the newest version of limewire? Do you have alot off incomplete files piling up or trying to download 15-20+ files at a time ?

Configure means changing your set up. If you mean user accounts this only applies if you or someone using your PC has changed something

I have only once had this problem and then it was harddiskspace
