Let's make sure you'll be able to successfully reactivate QuickBooks, suwrov357.

Normally, you can manage your QuickBooks Desktop account and services with the Customer Account Maintenance Portal (CAMPs). It's possible billing information is outdated, that's why you're unable to reactivate your account.

You can update your QuickBooks Desktop payment information to prevent issues. To do so, check out the steps below outlined in numbers:

1. Sign in to camps.intuit.com. Or learn more about signing in.
2. Find your app or subscription in the Products & Services list.
3. Select Details.
4. In the Billing Information section, locate Payment Method, then click Edit.
5. Update your information.
6. Hit  Save and Close.

Then, ensure QuickBooks update is installed so it will automatically download and install the latest update every now and then. You can also run the update manually if you like. 

However, if the issue continues, I suggest running QuickBooks Desktop Tool Hub to fix common problems. Here's how: 

1. Close QuickBooks.
2. We recommend you download the most recent version (1.6.0.3) of the QuickBooks Tool Hub. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). 
   Note: If you've already installed Tool Hub before, you can find out which version you have.
   1. Select the Home tab.
   2. Select About/What's New to view the version.
3. Open the file you downloaded (QuickBooksToolHub.exe).
4. Follow the on-screen steps to install and agree to the terms and conditions.
5. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.
   

 Note: If you can't find the icon, do a search in Windows for QuickBooks Tool Hub and select the app.
