Hi Jostein,

I did that, sorry should have mentioned it - it does not change the error.
I have the impression that the engine somehow chokes on bzip2/bunzip2
(tried both variants) - I've never read a *module with no systemId*
error message before and can't find somehting helpful by googling. And
the error message would be different, if the engine would not be able
to access bzip2/bunzip2 at all.

Kind Regards
Stefanie
