Hi, By the sound of your question, I'm assuming that you're talking about Quickbooks. The Accountant's copy isn't intended to be a full function copy of the company file. It's a copy that's good enough for financial review, not full-function operation. If you want to have all functions, you'll need to open the original company file (ending with .QBW). It would be the file that you created the accountant's copy from. Once you find the original company file, verify that you can open it, and once you've found it - you can delete the Accountant's copy. As long as the original company file isn't touched or damaged, you should be fine.
