Conquest of the Horde

This question has probably already been answered, but here goes.

Getting the infamous Unable to Validate Game version, even though there's supposedly no patch available. Did we downpatch or something? o.o

Check which build you're on. We just upped to 3.3.5a (build 12340) very recently, today I believe. You're likely still on build 12213.

That's the problem then. Mines 12213... I think that's what it said.

How do we patch it up then?

If you have an active retail account, change your realmlist back to retail, and try to log in. It will automatically have you download the patch.

Otherwise, check the Links section of the site - there's a link to the Patch Mirrors listing on Wowwiki.
