Using a number 08 file on a number 09 install
I have a Mac and an old Macbook Pro with Numbers '08 and a newer macbook pro running Numbers '09. When I try to send spreadsheets between the two I can't open them on the newer version. I have tried running Update 9.3 but that only seems to want to look at Keynote issues.
I could spend $25 downloading numbers 09 on my other machine(s) but then how will that version of Numbers '09 be any better able to open the Number '08 version of the spreadsheet?
This is SO un-Apple like it is driving me crazy. Why is a simple upgrade so difficult?
