My camera capture method below, no longer seems to works on my i-mate SP5 (HTC Tornado)..

The code worked and ran perfectly for the last few months, on both NETCF2..0 and the Beta of NetCF2.0 Service pack 1, but since I upgraded my device today to the new release candidate (non Beta), it no longer works and throws an InvalidOperation Exception on CameraCaptureDialog.ShowDialog(); method.

The .Net themselves seem to work alright, except the camera functionality no longer works

/**********************************************************************
* METHOD: startCamera
**********************************************************************/
public String startCamera(CameraCaptureMode incCaptureMode) {
/********************************************
* initiate Camera
********************************************/
CameraCaptureDialog ccd = new CameraCaptureDialog();

/********************************************
* Camera Settings
********************************************/
ccd.Mode = incCaptureMode;
ccd.Resolution = _CaptureSettings.Default_PictureSize;
ccd.StillQuality = _CaptureSettings.Default_Quality;
ccd.InitialDirectory = _Settings.Photo_DIRECTORY;

/********************************************
* Display Camera
********************************************/
ccd.ShowDialog();
return ccd.FileName;
}/************* End-Method ************/

Can you run it on emulator or another device What is the stack trace

Don't think it's the code as its fairly simple Camera capture code that I have used in numerous projects and which has been working for the last few months..

I was previously running it on NetCF2.0, then NetCF2.0 SP1 (Beta) without any difficulties, its only after upgrading to NetCF2.0 SP1 (Release) did it stop working, the new version of compact framework itself was installed successfully as all my .Net apps seem to work fine, its just the ones that use camera capture that fail..
