Hello my accountant and I just installed the new quickbooks desktop pro 2021 literally a week ago and I have been working on the program no problem backing it up as i go on a removable disk and all. today while working on the program it literally kicked me off and wont let me back in and everytime I try to click on quickbooks for it to open it shows me a message stating that there is an upgrade to contact support. what is going on with this program?
