BPW Install - Compile fail

We're installing BPW on Windows 2008 R2.

When it's compiling, the compile error pop up says:

"Failed to Compile - [BC_BSE_Organization_Flat_File_Source]
Composer (view) in [Lawson Catalog]

Reason:
There are unmapped column(s) Unmapped column(s):
Company Number
Accounting Unit
Company Accounting Unit
Company Name
Person Responsible
Company Nbr Name
Org Level 01

"
We stopped the compilation, and manually checked the BC_BSE_Organization_Flat_File_Source. I could see that all the columns were correctly mapped to the columns in the CSV source. So, I don't understand why it would fail to compile.

Any ideas what's going on?

Thanks,
