Facing the problem , while generating the login for technician

Hi 

I have downloaded In premise version of Manage engine Service desk plus and it is free as per web site 

I have created 4 technicians with the logins 

Now when I am trying to create 5th technician , it says 

Technician login count exceeds the license 

May I know , what is the issue here 

regards
