After deleted Asset\iTween folder, it generated compile errors
Assets/PlayMaker/Actions/iTween/iTweenLookFrom.cs(30,24): error CS0246: The type or namespace name `iTween' could not be found. Are you missing a using directive or an assembly reference?



Actually it was a working project and a mins ago, i remember i upgraded NGUI and it  happened. i am currently using

• Playmaker
• NGUI
• Playmaker + NGUI (https://hutonggames.fogbugz.com/?W1111)

could the error caused by an upgrade of NGUI?

After deleted Asset\iTween folder did you import iTween again from Playmaker Asset ?

NGUI can be problem i dont know because i didnt used it. This happened me when i updated iTween from asset store. After problem i deleted all iTween files from my project folder and imported it from Playmaker asset. That fixed my problem.

it generates different error now

I dont know why do you get Photon error. I have never used it.
Can you check your Gameobject from Inspector tab if it has any empty iTween scripts. I had problem like that.
