o I used Six Launcher to install Day Z. However when I Select a server and click join, it brings up a menu with a bunch of tanks and vehicle in the background and then crashes to my desktop with the following error: "Bad Serial number given in setup" Now I think this might be due to the fact that I didn't really load Operation Arrowhead (OA). Whenever I try and launch OA, I also get the following error when I click play on steam: "No entry bin\config.bin/CfgInGameUI/MPTTable.shadow " I click OK, and then Im prompted again with the following error: "Error compiling pixel shader PSSpecularAlpha:0" By the way I run Arma 2 just fine. Any help or direction as to what the hell is going on?
