As I have purchased a legitimate copy of Movie Edit Pro from you directly why do i have to keep repeatedly doing a license check? This is very irritating when I usually work off line.
This is a user forum; no one here works for Magix, so you didn't buy MEP from any of us.
You didn't mention which version that you have. I presume that it is 2015 and either basic, Plus or Premium.
Did you update to the latest patch? This problem was supposed to be mostly resolved, I believe. However, you will probably still have to connect to the internet once a month for the license check.
This is an anti-pirating method. The computer profile is registered with Magix and there is a monthly check. You can have two profiles, I believe, meaning that you can load MEP onto two computers, but only use one, and switch once a month.
If you are getting the license check every time that you open MEP, get the latest patch. There was a bug in a previous version that affected some users.
