upgrade

SUGGESTED

I was running Sage 50 Pro 2014 when my computer crashed and App was deleted.  I re-loaded my 2014 disk to install app but could not access my backup files as now Sage 50 Premium was somehow loaded onto my computer with a 10 day trial and my files were no longer compatible.   I purchased the new Sage 50 Pro 2021 and loaded it but my files are not compatible.  Sage Rep told me to go out now and buy the Premium Version $560.00.!!???    Will my files revert back to the Sage 50 Pro 2014 after the trial version is over as I do not even want the Premium version.
