Hey Retox!
'FsmStateAction' Not found means that it is having a problem finding playmaker. And since you mentioned that you have the latest PM would mean that there is a script inside playmaker that is throwing it off.
A couple of things you could do:
Remove the playmaker asset and reinstall it from the asset store.
Make a completely new package and install steam vr, and playmaker first, then the toolkit.
If you added or altered some scripts either remove them or revert them back to their original script.
If there is a problem with any of these solutions or it doesn't solve the problem, just let me know and we can move this to Skype.
