HELP! I've been using Limewire for years, and my version 4.9something got hung up a couple of weeks ago. I tried to upgrade to 4.12.11, and now I get this error message everytime "your save folder is not valid. It may have been deleted, you may not have permission to write to it, or there may be another problem. Please choose a different folder." I have tried all the fixes I found here in the forums, but nothing works. Using Windows XP and Java JRE 1.6.0_01; have searched unsuccessfully for .limewire file even in hidden files. Nothing.
