I was trying to image an open cluster with my ST-2000XMC but while I could run the PHD2 through Sequence Generator, Sequence Generator would not capture an image even though the timer was running.
Can you provide a log?
Sorry I took so long to reply but the email notification went to my spam folder.

Last night, I got it to work once but after that I was still having the same issues as before.
