I just remembered I didn't installed the latest drivers on this OS yet. I followed a guide on the fedoraforums about how to install that and that made Atlantica.exe work. But the patcher (AtlanticaRun.exe) still doesn't work, it keeps saying there's a maintenance. So I can launch the game directly from Atlantica.exe, but I can't play because it says I have to download the latest updates and I need the patcher for that... I also have a new log file for AtlanticaRun.exe: http://pastebin.com/0ydUS0PW Can you see a problem in there?
