That is like it was last year, you have to use the new version of Inventor to use the VKoP. You might be able to have someone with Inventor 10 save them as STEP files that you could open, then resave as Inventor files. But this does loose some things like constraints, and I think material properties. But if you can't use version 10, then redoing some parts of a file is better than doing them from scratch.
There are also a lot of parts that might help you in the
FIRST CAD Library.
