Hi Doug,

The OE is 8.0A (060825) with freshly replaced sample data. Same error occurs with the latest Ledger (AL) MCsamdata as well.

The "Codes" button I'm referring to is the "Codes" button on the Adagio button bar (hover above it and it says "Edit Currency Codes".

OK - Here's an update, on my desktop PC, I decided to try Editing the currency codes from the "Edit" menu instead and it opened but gave me a message about no default code. I put CAD and now the OE MCsamdata is OK but all of the other modules are still giving the original problem even from the Edit menu. Stranger still, my laptop OE data won't work even trying what I did on the desktop and naturally the laptop is the demo machine.

I'm going to try backing up MC*.* for the other MCsamdata folders and then copying the desktop OE MCsamdata files to the laptop.

Still hoping for a better solution/reason for the problem than what I stumbled upon though ???

Thanks, Pete
