Jail Prison Plugin and C3RewardSystem, Error

When i start the server, that run normally. But when i enter to the server, i got that in the console:

Code:

7/25/2012 6:37:31 PM
System.MissingMethodException: Method not found: 'Boolean TShockAPI.Utils.Kick(TShockAPI.TSPlayer, System.String, System.String)'.
  at JailPrison.Jail.OnUpdate()
  at System.Action.Invoke()
  at Hooks.GameHooks.OnUpdate(Boolean pre)
  at Terraria.Main.DedServ()
  at Terraria.ProgramServer.Main(String[] args)

Why i got that problem?
Note: I get that message when i have the JailPrison-More.dll on the serverplugin folder.

And, when i put the C3RewardSystem.dll on the serverplugins, i get that:

Code:

System.IO.FileNotFoundException: Could not load file or assembly 'C3Mod, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
File name: 'C3Mod, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'
  at C3RewardSystem.C3RewardSystem.Initialize()
  at PluginContainer.Initialize()
  at Terraria.ProgramServer.Initialize(Main main)
  at Terraria.ProgramServer.Main(String[] args)

I use the version 3.9 of tshock and i use the ignoreversion.
