What I have done in the past is download the free 2014 version and keep my older version on my computer. Use the new version to open the new files and save as an older version. then open that file in my older pro version.

Or you could email it to me and I'll convert and send back to you.

From what I can tell the BIM stuff requires a separate BIM software to integrate with -- so it seems like it won't help me out too much.
