Civil 3D 2014 won't open Civil 3D 2013 file - FATAL ERROR

[Anonymous]

I am trying to move all my project files into 2014 (basically trying to just open the files up in C3D 2014 and clicking save). I had some data shortcuts in the 2013 version as well.

It worked in all files except the most important one: The one that has my profiles and cross sections. Upon opening in 2014, I get this message:

FATAL ERROR: Unhandled Access Violation Reading 0xfea34218 Exception at ebea8902h.

I've tried deleting all cross sections and assemblies in 2013 and retrying, but to no avail. What the hell is happening? I've tried opening in recover and it "fixed errors" but am still getting a fatal error when I try to open. 

What else can I do to get this to work? Right now my only option appears to be to recreate all my work in 2014!

The users in the C3D forum may be of more help than here.
