I think,... take that with a grain of salt...all easy fixes for web based stuff is done.
HOWEVER, I think the game GUI MUST be updated with the new IP.,. just guessing, speculation due to the fix for new installs. It was looking for an needed file/update and could not reach that server. The GUI is probably hard wired with the old IP.. I can't manually DL maps either.....so mu weak conclusion is, it has to be updated.
it would be great if an update was the reason for these changes. Don't worry, I'm blue in the face too.
