Hello!
It's been a quite hectic wipe and we were forced to relocate to our backup host (213.170.70.111:2238). Many people have trouble getting the client to work.
If you follow these instructions it should work:
1. Run updater to grab factionXXX.dat files (with ip 94.103.86.46, port 4040)
2. Delete all cache files except default.cache
3. Download http://www.mediafire.com/?fefoztn1wrj which contains the new exe
4. Insert correct IP:Port into config tool (213.170.70.111:2238 right now)
5. Run the game.
6. Login (with default login and password, does not matter) and wait, then go to register
Last step is important, login first, then register. This is because the 2238 content is downloaded then.
Good luck!
