how do you clean a corrupted unity playmaker project ?

[t4d]

Hi all I had some issues here http://hutonggames.com/playmakerforum/index.php?topic=12626.0  and http://hutonggames.com/playmakerforum/index.php?topic=12630.0

but it seem now everythings work in a new clean project but the same actions same workflow don't work in the Main project ? I'm thinking I may be errors in the project or something ?  ( I upgrade to the latest Beta playmaker 1.8.1.f4 and running unity 5.3.4f1 )

what's the best way to check or clean a unity playmaker project of errors ?

getting these errors below when trying add force to a  Rigidbody

------------------------------------------------------------------------------------------
Can't add script behaviour PlayMakerFixedUpdate. The script needs to derive from MonoBehaviour!
UnityEngine.GameObject:AddComponent()
PlayMakerFSM:AddEventHandlerComponent(HideFlags)
PlayMakerFSM:AddEventHandlerComponents()
PlayMakerFSM:Init()
PlayMakerFSM:Awake()
