Hello,
You can see i have problems with BEX too. Always crashing joining a server, or later playing..i tried all. Reinstall windows, i have the drivers update...all type of drivers, dll's verified, all things done...and always the same, other friends of mine can play whitouht any difficulties and with the same pc characteristics,..seems some kind of omniscient and powerfull entity don't want to play this game. I gonna uninstall it and try it next year or something else..I hope someday it will work correctly.

You have my e-mail for any related question.
Good luck.
