Combining PDF's
I have 11 PDF's that I want to combine into one file. I select them all, right click and hit the "combine files in acrobat" option. The combine files menu comes up, all 11 documents are listed and I hit combine files. It goes though the process however when it's done I have an 11 page pdf of just the first PDF repeated 11 times. What am I missing? Thank you in advance for any assistance.
