Let's get this sorted out, @Nanny2011.

One of the possible reasons why the option to make account active isn't working is that your company file has data damage. Let's re-sort the account list to fix odd behavior in your Chart of Accounts. This way, you can make your account active again. Here's how:

1. Go to the Lists menu, then select Chart of Accounts.
2. From the Account drop-down, click Re-sort List.
3. Click OK to confirm.

Once done, you can now try activating the account again to double-check. If you get the same result, you'll want to utilize the Verify and Rebuild Utility tools to fix some data damage on your company file.

If the issue persists, I recommend contacting our QuickBooks Support Team. This way, they can further check on this matter and provide additional troubleshooting steps to get this resolved.

Please keep in touch if there's anything else I can do to help you succeed with QuickBooks. I've got your back.
