Suddenly cannot open Acrobat. Prompted to sign in, and then I get a "connect to internet" error.
Hello. I am suddenly unable to open Acrobat DC, which I purchased with my laptop in 2015 and registered. It says to sign in, and when I attempt to do so, it says to connect to the internet first even though I am already connected. When I click on customer support, a webpage opens saying my license expired or my version was illegal. I was supposed to have a perpetual license, as far as I knew. In fact, I can see the serial number I registered when I log in on the website under "Plans and payment"--"Products."
