6210 TOF not connecting

We have a 6210 TOF upgraded to a 6220 TOF unit had firmware 6.60 with mass hunter v4.00, changed the firmware of the unit to 6.422, we can ping the unit, when opening mass hunter we can see vacuum gauges and gas pressures, I can also vent the unit, but when i hit on, the unit doesnt do anything. Also i cannot connect the instrument to the diagnostic software. Error is 'Could not ftp/home/sc4/pipelineQtof/dynamicparams.txt from Can anyone offer some insight on this?
