An unexpected comand

My ProverXL 4030 was running fine with Universal Gcode Sender. I accidentally deleted UGS, redownloaded it, and now everything except jog commands work. When I try jog commands I can hear machine sending power to motors but no movement. Command prompt window says:an unexpected comand was executed by the controller. I have redownloaded UGS several times. Same result.

fixed; not sure why
