Mac "unable validate game version"Follow

Game has always run fine - tonight it says "Unable to validate game version. This may be caused by file corruption or the interference of another program. Please visit http://us.blizzard.com/support/article.xml?articleld=21370 ....."

And then it says "knowledge base unavailable."

Anyone know what is going on?

I don't play Blizzards WoW (Well I play wowscape close enough).

Have you try to download the most recent patch information and copy it manually to your directory? I had to do that a couple times I remember because something got screwed up.
