On Windows 8.1. I just renewed my subscription and when I run the older version, 5.12, it says a newer version is available. Then says I have to uninstall it. I went to programs and setting and uninstalled it. Rebooted. It's still listed in the all programs menu and when I try to run it it says it's a trial. When I try to upgrade it it says to uninstall the old one, but it's no longer listed in programs and settings.
