Problems

It seems like a fun game, but I cant get past the nickname part. Whenever I enter a name, it keeps telling me only English characters and numbers can be used, even though thats what Im using. I cant get past it at all. I dont know if its just a glitch or what, but please fix it, or better yet, tell me what Im doing wrong. The game itself looks interesting and I would really like to try it.
