Hi Colum
I think that will only allow downloading the service release
file(s). That would probably only work if they had already
performed the upgrade from 9.0 to 9.1.
I'll take a peek and see if I have a CD copy of 9.1. If so,
I'll see about posting it for download. Unless you want to try
Colum. Even if you have been using it as a coaster, I find CDs to
be amazingly resilient and will often allow being read in spite of
obvious scratches and damage.
Cheers... Rick
