boriz 1 Posted May 8, 2012 (edited) Good day! I have this serious problem with ARMA2: OA, BAF and PMC. After clicking on Play from Steam's Library I get this error twice in a row: "Can't find ARMA2:OA serial number in registry. " Then I get this error: "No entry 'bin\config.bin/CfgInGameUI/MPTable.shadow'." Sometimes I get error like this one: "failed to install application correctly." Then the game starts but immediately quits with this error: "Error compiling pixel shader PSSpecularAlpha:0" This happens everytime I start these games and I never managed them to work. The only game that I can play without any problems is ARMA 2 which runs smoothly on highest details. I already tried to reinstall them multiple times and used verified game's files without any change. I think the first error is the main issue but I don't know how to solve any of these. Could somebody please help me to fix these problems? Edited May 9, 2012 by Boriz fixed Share this post Link to post Share on other sites

boriz 1 Posted May 9, 2012 Thank you! It works! I had only time to try OA which works without any problems (so far). I think the rest of the DLCs should work fine. Share this post Link to post Share on other sites
