Sequence Generator Pro connects to guide camera but not the main camera!

Main Camera: ASI6200MM-pro
Guide Camera: ASI174mm-mini

I have downloaded the latest ASCOM and ZWO camera drivers. SGP recognizes the guide camera but is unable to detect the main camera. I have not made any changes to my setup and it has worked flawlessly for 1.5 years up until last night. How should I troubleshoot this problem?
