How to submit Gaussian jobs in materials studio?

Dear MS gurus,

I have a gaussian input file (dihedral_scan.ginf), but I don't know how to run a gaussian job from materials studio using this file. The gaussian interface does not have opt=modredundant, so I had to create this file somewhere else. Now, how can I run it? When I do Modules->Gaussian->Calculation->Files->Run Files, it complains with error ".xsd file not found"

Here's the file

%chk=me8t8.chk

%Mem=1012MB

%NProcShared=4

# B3LYP/6-311G opt=modredundant

Dihedral scan O1-S1-C4-H10 every 6 degrees for 20 steps
