Just the crash file.  However...

That's puzzling.  How did you generate the crash dump?  I remember that message but not what causes it (if I ever knew).

Perhaps it wants to read the defaults.  If so, copying the monitor SIL file would take care of that.

Is the system on which you're running this ANALYS run using the same monitor as the failed system?  Maybe that's the issue.  If ANALYS is using current monitor offsets to find data structures in the dump file, that won't work if you're analyzing a dump from a different system.
