Sudden problems
 

I've been using the OSX version for some time now. Yesterday suddenly Limewire refused to start. The icon appeared in the dock, and disappeared again. I trashed it and wanted to reinstall using Expander. Download was OK, it was expanded allright, but as soon as I clicked the installer it popped up in the dock immediately disappearing again, without doing anything. Anybody got an idea? I'm clueless.

Btw I'm using OSX v. 10.1.5
Thx S.
