Odd!

I'm not sure how the Windows installer works, but on OSX, the installer upgrades the current version. You should probably download a new installer.

Sounds like you might have something to send to bugs@limewire.com

If you look in the Tools->Options->Sample Bug Report, you can copy all the info there to send too (just snip out the sample java crash). It saves having to list many of the specific details that the developers need to get some context for your problem.

Sorry to hear the searches were worse.

Cheers
