I have a RAM failure on my Merlin Legend CKE4 R7 V9, so I purchased a refurbished CKE4 R7 V10. (I assumed that CKE4 Release 7, any version 9 or greater would be OK) I powered down the system, removed the original processor (V9) and installed the new (V10) processor and put my translation memory (PCMCIA) card into the version 10 processor. The system comes up. I set the date and time and proceeded to do a restore. The system validates that a good back up file is on the card, then I get a message, "RESTORE STOPPED; Board mismatch between control unit and file". I also have a win SPM (Ver 6.26) backup which I tried to restore; Similar error message (board mismatch). I feel that the new processor is running fine, as it starts up fine and allows me access to programming functions (also, no alarm light). Any recommendations are greatly appreciated! Thanks in advance
