I have a pending case on support because my Acrobat won`t activate on my Subscription any more. I think i might have run a java update the same day I got my problem, but im a little unsure if it was the same day or not... could that be the problem? and if so, how do I fix it? I`ve had support by desktop takeover, but he just reinstalled Acrobat and then i lost the supportguy I was talking to since I had to reboot. Now they are taking it up with the senior team apperantly, but it is taking forever and I need to use the program for work...
The orign problem was unable to validate a online activation (that had been working for 5 months without this suddenly poping up)
We don't know which version of Acrobat you are using and on what operating system, so here is a stab in the dark: Take a look at this old forum question, it has an answer by an Adobe employee which might solve your problem too. This would apply to Acrobat XI on Windows.
