Skyrc toro TS120A esc

[jackh84]

I bought a 2nd hand car with a skyrc toro ts120a blue aluminium case esc. I already have a skyrc prog box which appears to be the compatible one. It will connect but when I attempt to alter settings ie reverse motor direction it wont save the change and the star indicator remains where it was. As it stands my kf buggy wont go forward only backwards. Does anyone have any advise on this please many thanks. Also I have no manual on this esc and when I tried to download from website it downloads the esc for 1s not mine.
