BC2 moved to zloemu, authorization too.
Client update http://zloemu.org/files/bc2/Client.zip
Server update http://zloemu.org/files/bc2/Srv.zip
Now server login&pass used in bat file: -zlogin test -zpass test DO NOT USE ServerPass. If you have some servers in Win32Game.cfg - remove them.
If you want move stats from old personas - auth on zloemu, go to http://bc2.zloemu.org/transfer and login with OLD FORUM account, select persona to move, if have more than one, done. If was more then one persona - create another account on zloemu for each, because only one persona allowed now, with name from site.
Delete persona in game - will just wipe all data from it.
