thanks ingolf for your help, but it didn't work for me.
finally I got it fixed and here are the steps i did.
first I deleted all the files in these directories:
C:/users/public/documents/pinnacle/program files (x86)/Pinnacle/studio14/Programs/PlugIns/RTFx
C:/programs (x86)/Pinnacle/Studio 14/Plugins/RTFx/HfxXML
C:/ProgramData/Pinnacle/Pinnacle Studio Ultimate Collection/
then I made a copy of the c:/programs (x86)/Pinnacle/Studio 14/Plugins/RTFx/JPsEffects.fex and placed it to my desktop. then I overwrite the original JPsEffects.fex with the copied one (I know this sounds strange but that’s what JP told me to do :))
finally I started studio 14 as administrator. and there they are, the JPsEffects
