PSPICE Simulation model HF900 Error "incorrect number of interface nodes..."

Hello all, I want to run your PSPICE model of a flyback converter using HF900, but the simulation doesn’t run. It generates the error “ERROR(ORPSIM-15461): Incorrect number of interface nodes for X_U38.X_U72. ERROR(ORPSIM-15461): Incorrect number of interface nodes for X_U38.X_U129. ERROR(ORPSIM-15461): Incorrect number of interface nodes for X_U38.X_U132.” Please can you help to solve the problem? Many thanks!
