Odd license error on start

The client has a license for 1000 users but we are getting “you are not licensed for this many users” errors after about 6 logging on. Anyone have any ideas as to the cause?

Nevermind, solved my own issue. I looked at the license myself and it only has 6 sessions, not a thousand like I was told.

you were using a developers licence [}:)] which you should not have.
