I run into an issue with Acrobat Pro DC, when combining twp pdf files, using the COMBINE FILE TOOL. After I use this feature successfully two or three times, combining 2 files into one, the third or fourth time, it will stop working after I click on the "Add Files" button in the pop-up window. A dark grey screen appears instead of the combined temp document. In order to keep going, I need to close the application and reopen it and choose the files to combine again.
Is there a solution to it?
hi I am having similar difficulties. Did you find a solution?
