So you just Recently Updated Versions of LW ??
Sometimes it seems that a corruption appears when Updating.
Try these suggestions by LOTR's.
I'd suggest deleting your LW preferences folder, then reinstalling LW using the OFFLINE installer.
1. Delete your LW Preferences folder whilst LW is
closed; instructions here:
Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.) OR if using VISTA see
LimeWire Pref Folder in Vista
2. Uninstall LW using the Start menu -> All Programs -> LW -> Uninstall.
3. Run either or both of these utilities to clean up registry:
Crap Cleaner or / &
Microsoft Windows Install Clean Up
4. Reinstall LW using this OFFLINE installer:
