Error while trying to follow tutorial

Hello, I've tried to follow the Radioss' Bird Strike tutorial, but whenever I try to run the solver, I get this error:

ERROR ID :   257
** ERROR TH GROUP
 .. GEOMETRY PLOT FILE
 .. ERROR ==> NO RESTART FILE
     ERROR TERMINATION
     ------------------

And in the .out file, there is:

<?xml version="1.0" encoding="UTF-8"?>

Any help with this? thanks
