Cannot save file. Bad parameter. Potential Solution

First, I did not solve this problem on my own.  I found this answer posted somewhere, but I neglected to find the link.  I'm sorry.  I would not have been able to figure that out...

The issue.  I was trying to "Combine Files into one Single PDF."  After adding all my necessary files I "combined" with no issue.  Then I went to save and was told I could not.  There was a "bad parameter."  There were not any noticible issues with any of the files to start with - they were all "added" with no issue.

I did some searching online and somewhere it mentioned "Exporting" the file into a "Postscript."  That's how I saved the file.  I then went back, clicked on the file, and it opened up in Adobe Distiller.  This program then resaved the file as a PDF.  Thus, I got the file saved in the necessary format.
