Invalid files
 

One day i went to open limewire and i searched for something but nothing was coming up (even though i had searched it before and tons of things had come up). I went to the limewire website and went to download the new beta version to see if that would help. when i first went to install it, it said close the program then click retry. so i did. it still said i hadnt. well, i got past that and near the end of the installation it said i had invalid or corrupted files and now it wont work. i have tried to uninstall it but i cant find it in the start menu or in the control panal. how can i uninstal it now?
