Error running application in windows mobile

Hi,
I just created CAB installer using visual studio 2008. It is installing properly.
When i run the application it throws "The file cannot be opened. Either it is not signed with trusted certificate, or one of its components can not be found..."

I used the test certificate available in windows SDK folder : "TestCert_Privileged.pfx" to create my solutions.

My device is upgradeted to WM 6.1 ercently. Other application like google Map is installing properly.

Pls advice me to solve my pronlem. I am just learning c#.

thanks
Rags

re: Error running application in windows mobile

Have you tried totally re-creating the CAB project?

Some times this can happen when installing an app to the storage card and not the device, have you tried it on the device?
