I am getting the following Bluebeam Revu x64: Error "An item with the same key has already been added." This appears when opening a session. Some sessions are new to me and many are sessions in which I have previously worked. Once I click OK, the message goes away. Then, when hovering over a file in the documents list, the small preview looks normal, however, when attempting to open it, I get a blank document. Sometimes a few, but not all, of my comments from a prior log-in appear.
I am currently using Bluebeam Revu 2017.0.40. It has been uninstalled with all files and registry keys/information removed before reinstalling the software. My IT person also downloaded and installed the 2019 trial version, but the same issue occurs.
Please see photo of the error. Any suggestions will be much appreciated!
