Teamspeak 3 License Error?

Hi,

I am setting up my server again after someone completely broke it.

I've completely removed the directory that previously contained the old Teamspeak server in /home. I re-downloaded the server files, extracted them, placed my licensekey.dat file in the directory. Used Screen -S to run the server file in, and I get this error message about there being too many slots?

Any ideas?

Thanks
