>No its a com interop HRESULT type of error no real details

I assume there's nothing in the log files ?

You might just glean something from the HRESULT.
If the third bit if '0' it's a MS error, if not it's (in your case) Crystal. The Facility code might also reveal something.

Seems to me the most likely underlying cause is a permissions isuue ?
