Old iMac numbers 08, new Mac Book pro won't let me open numbers without converting to Numbers 09
I bought a new Mac Book Pro and when moving my Numbers and Pages files to the new computer it will not allow me to open the files until I update them to Numbers 09 first. On my iMac I was running Numbers 08. Any suggestions how to tackle this issue?
Thanks,
iPhone 5, Mac OS X (10.7.5)
