Import Export of Price List

SUGGESTED

Hello - I have a client who currently uses Sage 50 Quantum. He wants to quickly adjust his inventory prices so I had suggested he export his Price List, make the adjustments there and then import the amended copy. When we try to import we get this error message

:

How do I figure out what why I am having a file version mismatch. We've tried exporting directly to an Excel spreadsheet and we've tried exporting a .csv file first. After testing and adjusting only a few line item prices we tried to import and both times we get the above message. I confess I am not very "techy" so any assistance would be greatly appreciated.

Thank you
