I'm delighted that you decided to make use of the QBCommunity, this discussion space is bustling with activity and we are all learning more and more from each other every day.
The first thing to try when you cannot access a specific area of QuickBooks is to clear your browser cache by pressing CTRL+ALT+DEL. If that does not work, try accessing QuickBooks using a different login name if available.
If that does not solve your issue, it would be wise to reach out to support directly via phone or chat. https://help.quickbooks.intuit.com/en_AU/contact.
