How to finally run an input file via VISED/MCNP5 without error?

[nuclearsneke]

TL;DR

MCNP and eof error

Howdy, my fellow nuclear colleagues!

I am new to MCNP5 and currently I am trying to simulate something simple like a sphere of UO2 to calculate its critical size.
Whenever I run my file via MCNP5 or Vised, I get an error message like

bad trouble in subroutine pass1 of imcn

unexpected eof in file uo2crit0

I understand that problem is somewhere in geometry sector, because when I cut off all the lines above the geometry section, visual editor still crashes with lines specified before.

Detes are in the files attached.

Hi,

You have ? chars where I would expect empty lines. When I fix that it seems to work for me. Checked in Ljnux.
