Timeslips 2016 Login

We just upgraded to Timeslips 2016 and when I tried to log in this morning, I got an error that "there are not enough licenses to allow use of the program".  I was able to find the one user who could log in and went to Station Administrator, Options, Licenses in Use and cleared all of the licenses but I need to know how to set the program up so I don't have to do this every time.
