I'm having the same error -- "The procedure entry point ChangeWindowMessageFilter could not be located in the dynamic link library USER32.dll". I'm running Windows XP, if that information helps. Reinstalled r76 and everything works fine on the same machine.
Yep, sorry for late reply on this one, but this problem only affected the setup in the first hour or so of installs before I fixed it. I suppose that's the busiest hour though since we do all the facebook/twitter promo as soon as it goes up. In future if I do that again I'll try to make it clearer that it's been updated, sorry for the confusion.
tl;dr download r77 again and it should workAshley2012-01-28 23:25:47
