Toon Boom 5 coloring crash

I purchased Toon Boom 5 a few months ago. Though I love the program I am, more times than not, getting an error message and/or cdt when coloring… I’ve updated vc drivers and more than meet the recommended system requirements… Any help would be GREATLY appreciated!
I’m running windows 7 on an amd tripple core, 1 gb ram, and a 1 gb Geforce gtx 550 ti

Try disabling the Aero Desktop theme by right-clicking the desktop, selecting “Personalize” and scrolling to the bottom to select a "Basic and High-Contrast"
theme instead of an Aero one.
