You've helped us so much with water chemistry, maybe I can return the favor with a little spreadsheet help?
The programs should
be able to read older versions, but I have seen Microsoft screw this up in the past. A couple ideas:
1) Rather than just double-clicking the file, or right-click and 'open', try going to your spreadsheet program and selecting File/Open from the menu of the spreadsheet program, and drill down to where the file is. You might have a problem where the file is not associated with your newer program - this should get around that.
2) Download LibreOffice. This is open source and free, and they will load just about anything (macros can be a problem though).
