Crash Crash Crash it is like watching a NASCAR Martinsville Race.
I do not know what your programmers did to the Adobe products in the 2018 version but all Acrobat and Illustrator keep doing is crashing my computer. I reinstalled 2017 Illustrator but there is not a rollback for Acrobat. Please tell your programmers that "Just because you can does not mean you should"
I am sorry for the inconvenience you are facing, next time you see Acrobat crash, can you please save the crash logs and attach them here, it will help us to narrow down the issue.
