Adobe Acrobat Pro DC

Adobe Acrobat Pro DC crashes randomly in Windows 10 after working with several files. I have had this issue on multiple PCs and it has been going on for months. Today Oct. 31, 2016 I had a crash happen on a new PC and which has the most recent updates applied. I am opening pdfs that have vector files, raster images, and text in them from Revit. The crash occurs while making red line notes in the pdfs. In years past this has not been an issue. I am ready to switch to a different software pdf editor if this continues, since all work edited is non-recoverable if you don't do a save before the sudden crash occurs.
