Pro Version License key keeps falling off

I have the Pro Version. About once a week I have to re-enter my License because it says my computer is not activated. This is so annoying. How can I fix it?

Hi hzq9dh…

1./ How many licenses do you have?
2./ On how many computers do you have EMC installed?
