Importing from FIRST Library into Autodesk Inventor

I am currently trying to draw our robot’s frame in autodesk. However, I cannot seem to import any of the provided parts from FIRST. Does anyone have any solutions to this problem?

I assume your running Inventor 2009 correct?, because the files aren’t backwards compatible. I had no problems opening files from both the FIRST KoP or the FIRST CAD Library

Oh I see. So, if you don’t mind me asking, how did you open them? And yes I am using Inventor 2009.

Well, are you sure you even have the files to begin with?
