Unable to create an IFX instance for PEM fasteners

I am using Creo Parametric Release 8.0 and Datecode8.0.5.0

When using IFX I am unable to create an instance for PEM fasteners. I set the folder to create the part files and then select any of the OOTB dat files provided for PEM fasteners and CREO returns a PRO TK error. I have had no problems when creating any other type of nut, washer or screw, it is only PEM fasteners that do not work.
I have noticed that there are no nut_80.prt or nut_99.prt files in my folder C:\PTC\Creo 8.0.5.0\Common Files\ifx\parts\ifx_fastener_templates\nuts (if that is relevant)

Here are the errors that I faced
Error message reads "An unknown error occurred (PRO_TK_E_NOT_FOUND)
