Hi Mike

That's a sign of an incomplete installation. It might be from this upgrade or from one in the past.

Check the size of the file and compare it to the other files in the Ledger folder. If it is almost the same size as another file in that folder, you are halfway to figuring out what to do. But the other half is more complicated.

If you are experiencing problems running Ledger or printing financials, you might be better off re-installing from scratch.
