I've installed the most recent Limewire version today and re-registered $. I have no problems doing downloads and uploads. My problem is that About Limerwire, Preferences, and Tools/Statistics don't work at all. I re-installed/de-installed 5 times with the same result. I even manual cleared out any preference files that may have lingered and deleted any references to Limewire before the re-installs. Any ideas to correct the situation?

I had the same problem when I upgraded to pro 2.7. ( No preferences , tools)I ran a search for all limewire files from the earlier version and trashed everything except my shared files. Then I installed pro 2.7, Everything is fine so far. Hope this helps.
