Try checking the box and starting the game offline, and then quitting and going online. I think there is a little bug in that once the box is checked, the program should load the textures at startup, and not wait till you enter an arena - unless diff arenas need diff textures - I dunno - I don't think they do as starting the program offline first eliminates the loading when you go online. My hunch is connections are timing out while the program loads the textures into memory.
