Question about Arenas (User)

Since I am starving for more tracks, is there any way I can play the arenas as a single player?
One more question, on the Dishes track a lot of the textures seems to be gone or marked with "illegal texture" or something like that.... Is that still a good track?
Thanks in advance everyone and thank you for your hard work! This is one extremely fun and addictive game.
