Sorry, I can't help you, not familiar with PS Cockpit/DCS
Shep had suggested looking at the error log file
you will notice some error in the DCS log file (...\Saved Games\DCS\Logs\DCS.log)
Your screen shot doesn't show what the error was, or where it occurred?
Was line 41 (MainPanel Declaration) the problem? or line 43 (the DED line)? or the possible duplicate GetDevice(27) in lines 44-45 (regarding PFLD and CMDS)?
You can try to email Shep directly (click on the envelope icon below Shep's callsign)

He will probably need the specific error logs to help you, but try reaching hiim
