No option for Jt file in ProE

If I run ptcsetup for ProE wildfire 4, it shows the "Interface for JT" as already installed, but I can't find .jt when I try to open or save a file. Is there something else I have to enable in order to work with .jt files? Should I try to reinstall?

Alternatively, how do I know if I actually have the jt interface installed properly?

Thanks,

Yeoung
