Changed CD key but problem with DayZ Commander

Problem is simple I changed my CD key I do not run > > STEAM < < I only run DayZ Commander. When I want to join a server it gives a black screen and suddenly '' bad serial key '' appears any fixed people?

1 You ma have entered it in the wrong format. 2 It is a bad key. All of my keys are tested working before you purchase, but there are always exceptions. I see you posted my thread but I didn't see any feedback so you may have bought elsewhere.

I am not acutally paying for codes since I ain't got a job IRL ( which I try to get but isn't working ) I would appreciate it if you give me a free on tough, since I am bored as .... right now.
