cannot access "my documents" from "start" menu
 

what do i do? I cant access my documents, my music, control panel, my computer or my network places. This never happened before i downloaded limewire.

Then go there directly. It sounds like your shortcut might be corrupt. Open my computer, & go from there. It sounds like a reboot in safe mode is in order & repair using disk utilities (particularly 3rd party ones) & use your anti-virus program to check your system over.
