Welcome to the Community. Allow me to provide additional information about the error "3371 status code 11103" in QuickBooks and get you back to business.
Yes, @Lexiesmemere is correct, the error that you received is a license issue. To get this resolved, you can check out this article for the troubleshooting steps: Error 3371: Could not initialize license properties.
On the other hand, QuickBooks 2013 is one of the unsupported version, which can also be the reason for the error that you're getting. I'd suggest upgrading your QuickBooks to the latest version so you can run your business easier and faster.
If you wish to upgrade, you can check out this article on how to do the process: Upgrade or convert your company file to a new QuickBooks Desktop version.
Please let me know if you need further assistance about this concern. I'm always here to lend a hand. Have a good one!
