What now? I have an account, it shows up on the profile page. however, when it attempts to start the game it gives me the 12029 error code. I try to log on through
http://www.maniaplanet.com and I get as far as the log in screen and I get that the server "mp05.maniaplanet.com" "This page can’t be displayed". And finally, yes internet explorer *which I DONT use) is online.
