I apologize for the difficulties in installing. I will look into it more in depth. In the meantime, one issue might be that the current alpha version of the installer was not built with all of the assets that have been added to the world since the installer was built. As such, the program may need to stream the assets when they are encountered in the game. The character creation area has its own separate music, so it may be taking some time as that music is loaded onto your pc.
Try letting the program stay at the character creation point for some time, then closing the client, logging back in and trying again.
I will study if there are any other problems with that point of the game. Thank you very much for your patience on this matter; as we progress in development we will be able to build a new installer that preloads all of the assets to alleviate the longer loading times sometimes initially encountered.
