I'm having the same exact problem. It was running fine when I had 1.7.2 installed, updated to 1.7.2.3 and installed the latest beta and was getting waiting for host error. I rolled back to 94876 beta and it allowed me to connect to hosts, but when i joined the game from lobby and the load screen appeared it would freeze when it was almost done then it crashed to desktop. This is the error I got on the desktop crash. I've tried uninstall Battle Eye from the Battle Eye folder in expansion and re-installing through steam. I've also tried manually updating the .dll files from the site & nothing is working Problem signature: Problem Event Name: APPCRASH Application Name: ArmA2OA.exe Application Version: 1.61.94.876 Application Timestamp: 4ffef77f Fault Module Name: BEClient.dll Fault Module Version: 0.0.0.0 Fault Module Timestamp: 50001d06 Exception Code: c0000005 Exception Offset: 00003925 OS Version: 6.1.7601.2.1.0.256.48 Locale ID: 1033 Additional Information 1: 0a9e Additional Information 2: 0a9e372d3b4ad19135b953a78882e789 Additional Information 3: 0a9e Additional Information 4: 0a9e372d3b4ad19135b953a78882e789 If anyone could help it would be greatly appreciated. My friend is playing right now, but he's using Six Updater, which I dont I just launch through steam, but I have the correct launch options inputted and when I install beta patches I make sure to delete everything from the beta folder and I re-add my original Arma 2 OA exe application in the folder for it to patch
