You cannot go backwards with QuickBooks data. If you installed '15 and ran updates you have the most up to date version of '15. You have to purchase year version upgrades to match your '18 version. I do believe there is a way to install the '18 version with your current license to another computer but I'm not sure how. Speaker is your best friend for support calls.
