Did you try deleting the LW prefs folder from C:\Documents and Settings\*yourusername*\Application Data\limewire

The application data folder is "hidden". So you need to turn the option on to show hidden files & folders 'before' you search for it. Sample image here http://www.gnutellaforums.com/showpo...32&postcount=4

BTW for some people, changing compatibility mode to NT sometimes helps also.
