I recently downloaded Stellarmate 1.7.2 and have a similar problem using a CEM26. Apart from the initial spot on calibration window nothing seems to happen. I have attached a log file in the hope that someone could tell me what I am doing wrong. That way I will avoid what appears the arduous task of upgrading the Ioptron firmware as I will have to borrow my wife's Windows computer and try to remember how to operate it. Stellarmate 1.7.0 worked fine for calibration.
Thanks
Mike
