[0909] Main menu bug + crash to desktop

[Nuts!]

I've played PR .909 for the past couple days and not too many hiccups (laggy new maps, etc.), but today when I logged in the starting screen had reset itself. Buttons were labeled as MAIN_DEPLOYMENT, pr_connecting, PR_FILTER, etc. The Internet connection was definitely working, cuz I could see all the usual servers, but they were all red. When I tried to join one, the game quit to desktop, no error messages or anything else. Ill do a full uninstall/clean/reinstall, but has anyone else seen something like this?
