After running Arma 2 OA and going to the "new efficient format" it still didn't work, but after restarting my computer, reverting back to 1.7.3 then reinstalling 1.7.4.4 I managed to get into a server, hope this helps other people and sorry that I can't say definitively what did that trick. ***After dying and respawning I get the script restriction again...back to the drawing board
I second these, Balota still has graphical artifacts, same with the town hall area at Cherno. Also, I've been getting thrown back to the spawn points with my gear and everything, but it's just very aggravating.
