The problem with the project on MAX 4 ELAU Pacdrive

[Alex8]

Good afternoon. I hope you're doing well. Recently, we had a problem with the external power supply and the MC-4 unit stopped working. We fixed it. But the motors do not move when the control stroke is pressed. When connecting EPAS 4 to MAX 4, it writes an error: file SOURCE.PAK could not be transferred! and Sourcecode could not be read! When uploading another backup to the controller, EPAS 4 can upload the project from the MAX 4 controller without errors. Can you help me with this?

Replace the drive is the only solution 
if you did not get MC4 then ping me
