Using SAGE 50 Pro with a SAGE 50 Premium data file

Suggested

We have a SAGE 50 premium data file that was created on our old business partner's SAGE account.

We want to use that file in SAGE 50 Pro which is our SAGE account as we are no longer with that business partner and want to separate our file from his.

I have downloaded Sage 50 Pro but am unable to open the SAGE 50 premium data file.

Is there a way to make this work? We would prefer not to have to upgrade our software if it is not needed as the Premium edition is quite a bit more expensive and we do not need all the options it provides as this is just a small (sole proprietor) business with only 1 employee.

Please advise.

Thank you
