I can't open limewire in any version: I keep getting an error message:

"The application "LimeWire" didn't open because ">>ZGNativeUtilLib<<" couldn't be started"

I downloaded 2.7.9 and it seems to work fine in my other partition, but not on my main one; it started yesterday when I still was on 2.6. I tried disabling extensions, resetting the PRAM, installing it from another partition, reinstalling MRJ: I'm out of ideas.

I tried to install a new language set yesterday, and the problems started after that. I don't know if there's a connection or if it's just a coincidence.
