Problem with a Fagor 8020-GP CNC

After loosing all the machine parameters due to a power failure I had to re-enter each parameter one by one. I got the axes operating correctly, I am able to move them in both direction in Jog mode; However every time I run the general test (key “0”) on special modes the CNC displays error code 094: Parity T, G53 - G59 and it doesn’t let me run the machine in Automatic mode nor communicate with the interface (PC) to download any new program into the CNC.

Can anybody let me know what could be wrong?
I would be grateful for any reply.
