--- Comment #5 from Omar Moustafa omazhary@hotmail.com 2012-05-29 14:12:05 CDT --- I don't think the audio is the problem, it works fine throughout the entire character selection process. Neither is the installation, as I run it on my windows OS the same way and it doesn't complain.
What I have noticed is that it takes a considerable amount of time to do anything network-related. When checking the files at the launcher, it takes twice the time taken as on windows. The same happens when entering the game world. Then, it crashes.
