Hi! I'm a QB user.  I still have QB 2019 files, ones that don't require payroll.  I have not had any problems accessing them on my new computer, which I don't even think HAS Internet Explorer.  

Or are you completely unable to get into your files? The reply before mine said something about not being able to get into files.  There IS a work around for the login if you have the premier accountant version, just tell it you are not the administrator of the file and you don't have to login at all.  I NEVER login.
