Blank Screen

[Rhadaman]

Old MxO player here, just installed the game client and test server files and everything works great until the in game loading assets screen. It finishes loading but instead of taking me to the character select screen it just has a blank black screen with the green mouse pointer which I can move. I'm sure it is some graphics setting that I need to change but...how do I access those options? Is this a know issue? Thanks for any help/flame in advance!
