Error "Invalid Server Address"

@athidswu Hmm, that's interesting. I'm going to interpret the error message as a misleading one. Looking into the rare reports of this happening to others it appears to only affect the single player. If you go offline completely, I think this issue will still persist. 

I take i that you can play the online portion of the game without issue?

Can you try a Clean Boot to start, see if anything changes if you just start up the game with no other programs running?

I'm also throwing out a wild guess that you might have already addressed. Is your PC language one that uses the latin alphabet (usually English). If not, can you try creating an English Windows account and try that out?
