i purchased a license for the Lite version in July, 2017, and installed the current version then (11.2?). In September, the system began to fail on backups. upon investigating, I found the license key was no longer in the system. When entering the license key (from July), the system says the license in not valid for version 11.2. The license was for version 11. Why must I upgrade the license(and pay again) to go from one point release to the next? Why does the license key from July no longer work?
Thanks for your response.
