Data updated to a new file format and is not compatible with this version of the software

SOLVED

I am trying to open a file of a new company I am taking on.  I keep getting this error message:

"Data updated to a new file format and is not compatible with this version of the software"

I looked at my properties I have version 2014.3   

If I double click the data file instead of trying to open it once in Sage, It asks me if I want to allow Sage 2013 to make changes to my computer.

This makes me think the file was created using Sage 2013...?

I am worried that allowing Sage 2013 to make changes to my computer, it will reverse my program to 2013 on all of my companies.  Then I might not be able to read those....

How can I open this file?

Thank you!
