EBAB0013 error during restore attempt

I need to restore my 89 year old father's laptop from his Ghost 15 backups. The backups reside on an external disk. I can boot up to the Ghost 15 recovery CD but when I try to restore from the most recent recovery point, the following error message pops up and then after closing the message, it pops up again.

Error EBAB0013: A test that safeguards the integrity of the program failed unexpectedly. CHECK failed, PqiSectorFile:OpenForRead:.\PqiSectorFile.cpp(1269): Gpt version invalid or stream size incorrect.

I tried to restore using other recovery points but I receive the same message no matter which one is selected.

Any assistance I can get resolving this will be most appreciated.
