I, too, am having this problem with 3.1.1 on 2.4.2. I'm having problems with a few add-ons that show as being current. Blizz broke something in the latest bug "fix".
Mr. Dinesh, I have poured over these forums and have yet to see anything resembling a 'fix' for this issue. Where is the patch, fix, or updated version of Gatherer located, because it surely isn't on the main page or the download page (both still have the march 28th update as being the latest version)?
