It appears that the common thread here is that we are all running Windows 10.
I have the same issue. I manually uninstalled PunkBuster, reinstalled it from the official website, and ran the official updated. I still get kicked from every room for this corrupted memory error.
First, Windows 10 broke Red Alert 2, and now Bad Company 2? Dang.
[UPDATE]
I opened up the game's executable in the Origin folder and set it to run as Administrator in Windows 7 compatibility mode. That seemed to do the trick.
I have the same problem and I'm running windows 8.1
Still haven't found a solution :/
I've been having the same problem with Win10. I fixed it by running the game directly form the desktop shortcut in Win7 Compatibility mode. Right click the shortcut, etc. Hope that helps...
