Graphics Mill demo crashing Visual Studio 2008 in Win 7 64-bit

I am trying to assist a developer in our web department with a vector based solution to text before we purchase the full version of Graphics Mill. He is working on a Windows XP 32-bit environment, and I'm on a Windows 7 64-bit environment. He has written a demo that runs fine on his machine, however when I try to open it on mine, Visual Studio 2008 is crashing with the following information:

Description:
Stopped working

Problem signature:
Problem Event Name: CLR20r3
Problem Signature 01: devenv.exe
Problem Signature 02: 9.0.21022.8
Problem Signature 03: 47317b3d
Problem Signature 04: Aurigma.GraphicsMill.AjaxControls
Problem Signature 05: 5.5.3630.32317
Problem Signature 06: 4b1f909b
Problem Signature 07: 12e
Problem Signature 08: 0
Problem Signature 09: System.IO.FileLoadException
OS Version: 6.1.7600.2.0.0.256.48
Locale ID: 1033

At this point, I have to either close or restart the program. If I open a site that doesn't have Graphics Mill controls, it works fine.

I have ensured Visual C++ 2005 Runtime is installed and Ajax controls that Graphics Mill prompted for me to install are installed. I have tried both the 32-bit and 64-bit versions of Graphics Mill, and both do the same thing. Any help would be appreciated.

Thanks!!
