TeamCity Agent won't connect

Hi!

I have a connection issue. TeamCity local agent won't connect after update of TeamCity.
Now I have TeamCity-5.1.4 running on Debian Lenny server. Actually I have 3 agents. Two of them connected successfully and the third one is inactive. In administration Web UI I see "Unauthorized. Comment: Agent localhost-1 cannot be authorized because there is not enough licenses." But as far as I know the license allows me to run up to 3 agents.


Please, tell me. What is the reason?
