I've been playing a little over a week and I've enjoyed every second. Last night however when I attempted to login I would get stuck on the map loading screen. I downloaded everything again and it's still happening. I focus strictly on my Yellow Server account, but I decided to see what happens with the others so I tried Blue Server. When I did this the "map loading" bar filled but then it got stuck again. On Yellow Server the "map loading" bar didn't fill at all. Not sure if this info means anything. Any help is appreciated.

When was I making my account my name was required to be alphanumeric, yet in game I see multiple people without a number. Why is this?
