Capture NX2 on OSX Lion

I've been using capture NX2.2.8 without any problem on OSX lion.

Today all of a sudden it won't work?? On my laptop it still runs fine.... weird stuff.

I just read that it's not supported and I was totally oblivious to this fact
Anyone has a similar experience and a solution?

I did try to delete the plist in the preference folder, any more prefs I can trash?

thanks for any suggestions.
