Ok, a few weeks ago, without having done (to my knowledge) major changes to my system(running Windows 7 home premium 64-bit),
the game lobby of version 3599 starts malfunctioning.
It seems that no map can be selected in the lobby and thus a skirmish game cannot start.(A grey window appears in the upper right corner where the selected map should appear).
This problem does not occur when launching the 3621 version however.
Has this happened to any of you?
I 'd be grateful for any help.
