I'm sorry to report that I got home today and when I fired up the game it did some sort of small update and the dreaded 6034 error was back. I'm currently doing a complete reinstall. I'll let you know how I go. Like you said, what a cluster.
I found a fix for 6034. If you have an XBOX you neec to uninstall Data Pack 1 & 2. They are old updates and apparently conflict with the new update. I tried it last night and did a restart and it worked. Cheers.
Has anyone else run into Dev error 6034 in multiplayer ground war and quick game since the most recent update? 5 out of the 8 maps in ground war won't open and in fact crash the game. Quite a few quick game maps do the same.
I'm on an XBOX X.
