Zwift crashed on Mac and now resistance is higher then B4

I have been using my Emotion rollers with a Qubo smart trainer for 2 years now.  

Last week Zwift crashed mid ride. Restarted zwift and hopped back on and ever since then I have more resistance then usual.   I cant even use the big ring any more.  Called inside ride and we did a couple of test and we think my Qubo is fine.  Need help with this as it is very frustrating.

Thanks Hugh
