I got the same message a few times. Then I reinstalled the mission pack and was able to log in. Noticed server had been reset and I had a DDG+ and 3000 pp. Then I noticed the x-ships in the shipyard. Playing Fed, I right-clicked on XCB and got a black screen. Hitting ESC brought me back to the shipyards. Right clicked on the XCF (or whatever the frigate is) and got a black screen. Clicking on another ship (a regular ship) got me the ship schematics. I went ahead and bought the X-frigate. I also noticed the missions were now "Investigate", "Patrol", "Asteroid Base Defense", etc without the "ED#" in front. Tried the Investigate and the Asteroid Base Defense missions. Both of them started with the basic star field, no ship model and froze after the mission orders appeared on the screen...
