Are you on Windows or Mac? In Windows you can change the update preferences. If you are using the Windows Desktop program, the first thing I do after installing the program is change the Updater settings to ask me first. To change the Windows program Update Preferences settings go up To Online - Updater Preferences
It really reinstalled the whole program? It asked for the License Code again? Make sure your computer is the same way when you originally installed it. Like with no flash drives plugged in or plugged in if one was. It asked me again so I just closed the program and took out a flash drive that was plugged in and tried again. It worked. Or you may need to connect a flash drive or printer or something that was connected when you originally installed the program.
