Compatibility issues with DirectRT

[FONT=&quot][/FONT]Hello everyone,

I'm having a bit of trouble with compatibility from one version of DirectRT to the next. I have a study which runs from Media lab and uses DirectRT for an attention task within the experiment. The study works fine on our computers (Windows XP Professional) using these versions of MediaLab and DirectRT:
MediaLab: 2008.1.20
DirectRT: 2008.1.0.13

When I try to run our experiment on our newer computers, we have been running into issues once DirectRT comes into play. That is, the new computers will run the MediaLab stuff fine, it's just once we get to the first attention task (using DirectRT) that we run into issues. The computer just locks up and never actually opens the file to be able to run it. We are forced to escape out of the program. The newer computers are running on Windows 7 Enterprise (64bit). Here are the new computers MediaLab and DirectRT versions:
MediaLab: 2008.1.33c
DirectRT: 2010 beta version downloaded from this link:

We're not sure why the new computers are not running our files made from the slightly older versions. Can someone help us investigate this problem? I've also attached a sample attention task we are using in addition to our style file. Any help would be much appreciated!
