Game crashes on startup after joining 4.0 beta

[eager comet]

Any time I start the game after joining the beta, it crashes at the title screen. I've sent the crash reports, but wanted to know if anyone had any ideas, as there don't appear to be a lot of similar complaints in the forum.

Beta forum had a suggestion

I swear I looked for a beta forum and didn't find it. I may be blind. Thanks much.
