I have had some good sessions with the ASI1600MM-Cool and the latest SGP v2.5.1.14 release with ASCOM driver version v1.0.2.5 from ZWO. Yesterday, however, as I was trying to take a sequence of dark and bias frames at a new temperature for my dark library I encountered an issue where the sequence would work correctly for a few frames (sometimes as many as ~30, but usually just a couple) and then would hang while attempting to download a frame. If I waited long enough the sequence would abort. I am using Windows 8.1 Pro, the camera is directly connected to the computer with a USB 3.0 cable (provided with the camera), and I have tried restarting SGP, disconnecting everything from the camera to reset it, etc. but the problem persists. I was previously able to get through 5-6 hours of exposures using this same setup without issues.
I have attached sample logs of the problem occurring below. I can also provide the sequence file if it will be helpful, but this forum doesn't allow it to be attached due to file name extension restrictions.
