Hello there!
I was playing ArmA II (steam-version) for pretty long time. Everything was okay.
Then I tried to install Undead Mod and got some really annoying graphical bugs - twitchy models, missing textures, such things.
I've deleted undead mod completely, but bugs were still there.
I've reinstalled ArmA II - still there.
I deleted ArmA Operation Arrowhead, so only regular ArmA II left - still there.
I tried veryfying the integrity of game cache - 1 file is being redownloaded, but bugs are still there.
Now it is like that - I get in the main menu, watch graphical bugs for about 20-30sec, then game stops.
How can I fix this? I have ArmA II CO and BAF, but I need only my basic ArmA II to work.
