Inventor 2013 to 2012

Our school is currently using version 2012 of Inventor, but the part files are all built in 2013. Is there any significantly new files that we cant live without in this years collection? It looks like we will have to use last years models until we find a solution or model our own. Anyone else having this issue?

I created a 2013 KOP in STEP format. They are posted on the community in the same location as the 2013 KOP.

Email me if you have issues getting them.

You can also search on the KOP for identical 2012 parts and use the STEP files for the new 2013 parts such as the chassis.
