How do I make sure my combined PDF files are in the correct order?

After adding your files in 'Combine files', you will see small images (thumbnails) of each file. Click and drag these thumbnails to arrange them in the exact order you want them to appear in the final PDF. The file at the top of the list will be the first document in your new combined PDF.

What should I do if my combined PDF only shows the first file repeated many times?

This is a known issue. First, try saving each of your original source files again using 'Save As'. This can refresh their internal structure. If that doesn't work, try adding your files to the 'Combine files' tool one by one instead of all at once. As a last resort, go to 'Help' in Acrobat and choose 'Repair Installation'. This can fix deeper program problems.
