Potential Fatal Error in DirectRT

I've run into an issue using DirectRT. Often I'll get to the point in an medialab experiment where a DirectRT input file is called upon, and the program will freeze. Then when just trying to run the input file, directly from the DirectRT program, nothing happens. The way I have fixed this is to restart the computer and it seems to work again just fine, but the problem returns periodically, for no apparent reason.

Has anyone heard of this problem?

Is there any software on microsoft that i should be more conscious of it being "up to date?" I have lost more than one observation due to this problem. I am using V2010.
