No access to online Company File

We're in a terrible situation.  MYOB migrated our offline company file (we have been ongoing customers for 28 years on the PC stand alone version ) to the cloud version approx 6 weeks ago.  It was working OK initially until an upgrade was released a few weeks ago.  It would not open in the latest Version 7 and we ended up in a constant loop not able to access our company file.

I spent nearly 4 hours online with support and finally it was determined that there was a problem with our company file and the data experts would have to provide a fix.  The support person helped us reinstate Version 6 and we were instructed not to attempt to use Version 7 until the fix is done. We were given a timeline of 10 days for that to happen.

However, on 1 September, we are again unable to access our company file.  MYOB prompts us to upgrade to Version 7 but we can't until the fix is done.  So we go around in a loop unable to access our file.  I spent more hours attempting to get our MYOB AccountRight software working with the assistance of MYOB Support Chat to no avail.  We have now had to engage and pay an external IT company to assist us in resolving the issue. They have spent another hour on the phone with MYOB Support, and we still do not have a resolution.

So since, 1 September we have been unable to access our company file.  MYOB forced our software to upgrade from AccountRight 2026.6 to AccountRight 2026.7. The online database will not upgrade to version 2026.7, which means we are now completely unable to log into MYOB.

Attempting to uninstall version 2026.7 and reinstall version 2026.6 does not resolve the problem, as the software automatically upgrades itself again when it is opened.

We have also attempted to access MYOB through a web browser. This also prompts us to upgrade the database, but the database then becomes stuck in a continuous upgrade loop.

As a result, we are now completely locked out of our MYOB system.

This is no longer simply an IT inconvenience. Without access to MYOB, we have had to stand down staff in our warehouse, we are unable to access existing quotes and orders in our system, see our inventory, we cannot create invoices for products leaving our warehouse.  Our business has come to a grinding halt.

We need this issue escalated immediately and urgently resolved. We cannot continue waiting while our business-critical system remains inaccessible.

This situation is now costing the business financially through the external IT support we have been forced to engage, as well as the operational and shipping issues caused by being unable to create invoices and dispatch products.

Is there anyone on this forum with contacts within MYOB that can help.  We are desperate!
