Hi - I too am now having the problem all of you have experienced.  I have QB Pro 2020 desktop and payroll subscription. Cant get anyone to help at QB - in meetings or closed. The software starts to launch and then fails and locks up after I out y password in.... When I go to Task Manager and expand the QB file to close it, bring it forward, etc.  I have found an odd subset under my company file named "SQL Anywhere Personal Server". I suspect this is the problem but cant get anywhere. It s like a cat chasing it's tail.  I need assistance as I pay for a payroll service with QB.  Please respond ASAP.
