Error in inputing skc file in CarMaker " Invalid command name "IFile" "

Hello,
I was trying to input our kinematics design into Car Maker using SKC file from ipg Kinematics. I’m successful in creating the SKC file, when I tried to open the model in from the kinematics tab in the vehicle data set, there is an bug pop up 'Invalid command name “IFile” '. Anyone encountered this problem before? Or did I do something wrong in the setup proccess?
Thank you.

Dear Agun,
I encountered the same problem when I was trying to change the suspension kinematic from an SKC file to another SKC file of a self made model. It prompted me the same error message. I always did it this way, so I guess this is a bug in this new version.
