Suddenly receiving a pop up saying I'm on a free trial when I have a valid license of adobe acrobat XI
I’ve been using adobe acrobat pro XI for around 10 years in a printcenter. Suddenly when I open acrobat pro I’m getting a message saying that I’m on a free trial and have 30 days left. When I try to put my license back in I receive a message saying the license was either revoked or invalid. I spoke with adobe support but they can’t help me because acrobat pro XI is too old and it was a one time subscription.
I realize that the licensing servers have probably been shut off but is there any way I can keep using this software?
