Hi all, last year I updated my long running QB 2018 ent. because certain features stopped working. My company is winding down and the subscription fee is just too much. I need to go back to my QB2018 and revert my file to work with this version. The only solution I have been able to find was saving the file in portable format and importing it into the 2018 version, which I tried and it didn't work, giving me a similar error. Any help will be appreciated.
