eDrawings for Inventor

Our design office uses uses Inventor 2013 and I have downloaded eDrawings 2013 but every time I try and open an IPT or IAM file, eDrawings gives me an error saying "incompatible file type". I checked the release notes and they say that eDrawings 10.1 has added compatibility for Inventor 2013. Does anyone know what I can do to fix this?

Thank you,

Jereme
