kira153 10 Posted February 5, 2011 Yesterday, i bought combined op on steam. So this morning I wanted to launch the game and it didn't work. When I launch arma 2 it say "bad serial number given in setup" and when I launch OA it's "data file too short expansion/addons/structures_e.pbo . expected 676064447 B, got 644218880 B" and combined op doesn't work either. What can I do ? Share this post Link to post Share on other sites

Posta 10 Posted February 7, 2011 1. Try verifying your Steam cache. Don't recall the exact term, bur right-click in Steam. 2. Start Steam as an admin. (Actually this would be step #1. :) ) "expected 676064447 B, got 644218880 B" I got a similar error when using a bad RAMDISK app. A read-error that is. Sounds like corrupted files.
