I haven't contacted support yet, I will try uninstalling and re-installing Carrarra completely (it's a fresh install on a new machine anyway) and then contact them if that doesn't work.

My system is a Q6600 Quad core 2.4 Ghz on an Asus P5K motherboard with 4GB of DDRII 800 RAM with a Saphire Radeon HD3850 with the latest Catalyst drivers (8.5)
