I can now create datafiles!
I had 1.6.14a which I downloaded from this site, and thought that it was the latest version.
I just downloaded 1.6.16 from:
http://www.numinix.com/index.php?mai...roducts_id=756
uploaded the new files, did nothing else (no SQL updates) and now I can make datafiles.

Joy Joy Joy!
