Can no longer view portfolios

We have been creating / using portfolios for about 6 month with out any issues.  Today, I attempted to create an updated portfolio using Acrobat Pro 11.0.06.  My portfolio now displays an image with the message "for the best experience, open this PDF portfolio in Acrobat X or Adobe Reader X, or later.

I am using version XI of Acrobat and Reader.  I have used the repair installation option for both, and I have also recompiled my documents from word to pdf using Acrobat (instead of using the word option)

Any suggestions?

Thanks,

Frank
