I recently got a much-needed new PC. Over the past several months, I've been playing on the MrGreenGaming servers and racked up some GC under the username RudeDude2140a. When I press F6 and log in, it accepts my old username and password (the same one for the forum and GC site). However, the first time I logged in with the new computer, I was automatically assigned a different username (MurkyCurio76) which shows up in-game. All my GC and car customizations were gone too. Is there a way that I can recover my old progress? Even if that isn't possible, how can I get rid of this stupid username?
