hello everyone i'm using mfps kit in unity 5,and i have cursor problems,when i select team,and want to move with character i can't,i tried to fix this but it's too complicated if someone can help me please,i tried also to change to Cursor.lockState and save script,i can't save any script why?

Warning:

Assets/MFPS/Scripts/Weapon/bl_Gun.cs(165,21): warning CS0618: `UnityEngine.Screen.lockCursor' is obsolete: `Property lockCursor has been deprecated. Use Cursor.lockState and Cursor.visible instead.'

I believe Briner has a forum directed to support people like you for purchasers of his product(s). I recommend you go there.
