milkyway12 10 Posted June 30, 2010 (edited) Problem. Fresh install from steam , checked integreity of file , turned off fire wall. Windows Vista 64 bit lastest install. Cannot Open File 'Expansion/addons/air_e.pbo' What do i do ? I cant launch the game ---------- Post added at 03:00 PM ---------- Previous post was at 02:54 PM ---------- Ok , i deleted the BPO and the air_e file , and i am reinstalling both files if that doesnt work , i ll launch Arma 2 and hope i can play Arma OA from there lol . Until i get a response that is. :) FIXED , all i did is went in deleted the file that gave me the error message along with its BPO , did an integrity check (reinstalled the files) and wallah , it works. So if your having a problem with files , just delete and reinstall it :) Edited June 30, 2010 by milkyway12 Share this post Link to post Share on other sites
Lal 10 Posted July 4, 2010 I'm having the exact same problem, but I don't fully understand, did you delete only the two files, or the entire game? How do I do an integrity check? Share this post Link to post Share on other sites
