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

After you add files to Combine Files, you will see small pictures (thumbnails) of them. Drag these thumbnails up or down to change their order. Acrobat combines files from the top of this list to the bottom, so the order you set is important.

What should I do if Combine Files only shows the first document or freezes?

Try saving each original source file again using 'Save As' to refresh its internal structure. Add the files to the Combine Files tool one by one instead of all at once. Use the 'Help > Repair Installation' option in Acrobat to fix any software issues.
