Direto Offset and Calibration

[tonedez]

Greetings crew, i recently changed the belt (same as original) on my Direto, since doing so i have not been able to calibrate the trainer. It just says, 'start pedaling', nothing else happens so i just have to cancel it. The trainer is warmed up, wi-fi, internet, blu-tooth, Ant+ and all else is connected and enabled but no calibration is happening, please assist.

Also, can someone identify the Offset # on my Direto?
