I can feel the disappointment of not being able to use the Accountant Center, Kason Kellstrom.

But I'm here to help check what's causing the program not to get the Accountant Center feature to work. I've tried opening this feature using a sample file and it's working well.
 

I've attached a screenshot below as your visual guide.

You can try to open a sample file and if you're able to open the Accountant Center, make sure to run your QuickBooks as administrator.

If still not working on the real company file, I suggest getting back in touch with our QuickBooks Live Team. I know you've already contacted them, however, they need to gather the specific issue. For example, you can't open the Accountant Center, the Accountant Center is grayed out, or links from the Tools box won't open. That will help our Engineering Team can take action in the right place in the program.

Get back to me on how the contact goes by commenting below. I'll keep this post while waiting for your response. Take care always!
