Hi Barry

I used to run into this issue with Cashbook, most recently 17 years ago!

You need to create a new (empty) Cashbook dataset and create the various banks in it. Let's say it has an extension of .NEW and your regular data has an extension of .DAT.

Once you create the new empty dataset, you will want to copy three files for each bank from the new dataset to the live dataset, let's say there is a bank 01:

Copy CB01BTCR.NEW CB01BTCR.DAT
Copy CB01BTT1.NEW CB01BTT1.DAT
Copy CB01BTT2.NEW CB01BTT2.DAT

If that works, save those files for the next year - you will probably need them again.

If you aren't sure how to create a new dataset, I can do it for you - email me at steve@sschwartzcpa.com and I will email you the empty files. Tell me the bank numbers you have.
