WinMoSquare - .net cf initialization error

[designflaw]

I tried to search the forums but could not come up with anything worthwhile so thought I did post here for the gurus.

I have a windows 6.1 htc diamond phone with sprint. Its a cdma phone. I installed the WinMoSquare application but whenever I try to launch it, I get the following error

.net CF initialization error
To run this application, you must first install one of the following versions of the .NET compact framework: v3.5.9198. Contact your application publisher for instructions about obtaining the appropriate version of the .net compact framework.

The kicker is that I do have .net v3.5.9198 installed on my phone, and have select v3.5 as the framework to use with this application. I did this via the .net configuration tool. Also, if I look at the .net configuration tool it gives this information

.net compact framework versions installed:

3.5.9198.0
2.0.7045.0 (ROM)

Windows version:

PocketPC
5.2.20764

and on the 4th tab (application policy), I have selected the WinMoSquare application and choose 3.5.9198 to be used.

Does anyone know how to change the default .net version on windows 6.1?

Thanks,
