I'm running PT LE 5.0. One of my plug-ins froze my sessions every time I tried to use it. A friend of mine gave me the plug-ins in the first place, so he says just delete the old DAE folder and replace it with a new copy that he gave me. I dragged the old DAE folder to the trashcan and deleted it. I installed the new folder (not sure if I did it right, but I placed it into Sys Fold) now when I open a previously saved PT session it's saying Wave Shell 3.0 is missing. What can I do to fix that?
