I'm running Windows Vista basic and for some reason after installing Lime Wire it freezes in the (select files to share window), and it does it every single time!!!!! It doesn't even open Lime Wire...it just stops responding, with no error codes or anything...PLEASE HELP!!!!!

Best thing to do would probably be to try to un-install the present version of Limewire and start again. Download the latest version and see if you can install it and get going.
If you can't get it going then post back here and someone with more experience may be able to help you sort out your problems.
