Crashes all the time on my Mac Pro.

Im running the game on a Mac Pro under 10.7.5 using an ATI 5770 card and 6Gig of system memory. The game crashes every time I select a bot. If I go botless, the game crashes as soon as I try to initiate battle. The website has no real support forum and the manufacturers seem unresponsive on Facebook. I spent $10 on this thing, Id like to at least be able to play it. :(
