FBX has been there since A7 I think Do you have that latest version of your series?
MED only imports FBX
FBX export still works but you must insert fbx export plugin in med_plugins folder. For some reason they are no longer part of the A8 installation, but i guess that you can find it in A7. Btw i have them on my hard drive if someone needs.
@MatAllum: I'm glad you've solved the problem.
