I'll help you re-subscribe your QuickBooks Desktop, Catherine Mills.
Since, when you're unable to do so, I'd suggest reaching out to our QuickBooks Desktop Support team. They can take a closer look at your account and help you re-subscribe.
To help you navigate those features in the program, check out this link a guide: Get Started with QuickBooks Desktop
Feel free to let me know how the conversation goes below. I'm always here to help.
