You have shadow surfaces in yo
 
You have shadow surfaces in your Fluent mesh (i.e., internal faces set as wall). Try fluent3DMeshToFoam. It should handle them!

Nope. Looks like the 3D solver
 
Nope. Looks like the 3D solver is facing trouble too

Here is what I did and the message it gave.

You probably have DOS linefeed
 
You probably have DOS linefeeds instead of Unix linefeeds. Try running something like dos2unix to convert the file.

Looks like there were dos line
 
Looks like there were dos linefeeds because dos2unix did process the files. However, the
error persists when I use Fluent3DMeshtoFoam
(as well as FluentMeshtoFoam which I tried just in case that went through for some reason).
