My organization has just pushed out Office 2013, and one person has had trouble when she combines files to create a pdf. At first, it seems like the process works, but when it comes to the "Merging Files" stage, it hangs up - it doesn't even finish converting the first file. It stays like this for a very long time, then a small pop-up comes up and says "Acrobat failed to send a DDE command."
The reason I bring up Office 2013 is because before we pushed it out, it worked just fine with either the 2010 and 2007, and now I'm wondering if this problem is occurring because of our recent 2013 installations.
