Hi Jared,
The camera is in manual mode and exposure time set to "BULB". I only use this camera for imaging, so I never change the camera settings. It seems to work as normal in the EOS Utility.
I have never had to do anything strange, such as deleting .dlls to get it working - it was just "plug and play".
Out of interest, is there any way to use SGP to capture to the camera's SD card rather than downloading to the PC? This might be a temporary workaround.
Thanks,
John.
