L2J Some unexpected problem

[wutengsan]

Just compiled my l2jfree server (adding some anti hacks and quiz event) and when I try to start it the game servers throws this:

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 
	The method registerAdminCommandHandler(IAdminCommandHandler) in the type AdminCommandHandler is not applicable for the arguments (AdminCTFEngine)

	at net.sf.l2j.gameserver.handler.AdminCommandHandler.<init>(AdminCommandHandler.java:123)
	at net.sf.l2j.gameserver.handler.AdminCommandHandler.getInstance(AdminCommandHandler.java:107)
	at net.sf.l2j.gameserver.GameServer.<init>(GameServer.java:265)
	at net.sf.l2j.gameserver.GameServer.main(GameServer.java:396)

any1 knows what could go wrong?
Didn't mess with AdminCommandHandler.java nor AdminCTFEngine.java while adding those scripts.
