There is no copy protection. There is anti-piracy scripting. As long as you're not pirating it, AP code won't activate. So copying it to whatever device however many times, as long as you're not sharing it, giving it away, trying to sell it, or allowing others to use it without you benefiting - basically allowing one or more persons to use and benefit from your paid for copy while you are not simultaneously using it - is fair use, and will not trigger AP code.

Shannon, if I shared MLS 3.0 without selling it to a friend because he was in bad period with the university, did I triggered the AP code for me and/or my friend?

If two people are independently in possession of a copy - and only one person paid for one copy - then yes. You triggered it by committing piracy by "sharing it" and he committed piracy by accepting it and/or using it without having paid for it. Both of you will have to correct the situation to turn off the AP code. The easiest way to do that is for him to delete his copies and you to pay for a second copy and then give it to him.
