WeFly247 - Can't find PInvoke DLL 'Graphics.Native'

I am trying to get the WeFly247 application running on my Pocket PC (a Verizon XV6700), and I get the following error at runtime:

Can't find PInvoke DLL 'Graphics.Native'

It is unclear if I am supposed to replace 'Graphics.Native' with the native DLL for my device, and if so, what is the native graphics driver for my device. Did I miss something in the docs

I have Visual Studio 2005 installed and working properly. The application compiles and deploys successfully. But will not run.

Has anybody encountered this error Any suggestions on how to deal with it

Thanks,

DWD
