Solved Kicking players for moving to fast - Help!

My 1.2.3 server keeps kicking people, and I have looked everywhere, and got NoSpeedKick, (which didn't even work.) and it still kicks players when they join, and i can't find out why! heres what it say when someone joins and gets kicked:

Code:

And when I start the server, there are no errors. And if it helps, my server is port forwarded.

 

Remove NoSpeedKick, and go to your server properties and set flight to true.

 

Thanks
