As I understand the situation from Adobe blurb the software needs to check online that you are still licensed every 30 days. What is the consequence if on the 30 day you are unable to verify because you don't have an internet connection or there is a problem with the verification process (of course that would never happen in real life! )?
If the software simply stops working this could be catastrophic - deadline to meet and suddenly because you can't connect to the Net you can't use your software.
If there are problems with the verification process the software does give you a grace period to work on resolving connectivity issues before it stops working, so you can contact support for help getting it fixed.
Thanks for responding to my question. Please could you provide more specific information about the grace period and the process that occurs should you fail to verify over the Internet on Day 30?
This page has more info about the activation process
The software will tell you it needs to activate if it is unable to do so, the grace period is for seven days to the complete activation process.
