Qualle: http://www.cncworld.org/Apoc has posted on the official forums a note the say that the development team are close to fixing a bug certain people are experiencing causing the game to crash when loading the main menu. It is related to the online lobbys which are persistent throughout the menus:
New maps is always good news, and later on in the same thread he mentioned that they intend to release Worldbuilder in April!This is in regards to those getting the "frame rate" dropped error message, and/or crashing primarily right when the game loads in.
This IS NOT related to connection with the server errors that you experience randomly during a match. We're assessing that issue as well, but I would strongly encourage you to check your ISP provider as well. Yes, that is quite obvious, but I have to say it because that could be the culprit as well, unfortunately.
We're working on a patch that addresses the lobby crash errors and also includes some new MP maps and a host of other bug fixes.
