New Books - Old Version

SOLVED

I'm looking for some advice as I'm taking over books from an organization. I currently have the Sage 50 Pro 2019 version but the person I'm taking the books over from has a 2013 version. She put it on a USB stick for me to transfer the files but it won't work. She had trouble with her program, it stopped allowing her to backup and she hasn't updated the program (unsure why) She also didn't have the .SAI file on the USB stick which I know I need. This is the message I get.....is it because not all the files are on the USB stick or because her version is just too old? Any advice would be greatly appreciated.
