Hi John,

Hmmm... can't think of any good reason why that would happen,
unless something has knocked out Guide's access to the CD-ROM. Have you
added or removed any drives? It could be that Guide is looking for data
on, say, drive d:, which has now been moved to drive e: or some such.

(In a perfect world, you could mount a drive as a particular letter
and leave it that way... in fact, some CD and DVD drives _can_ be
specified with a fixed letter; you can go into Device Manager, select
the properties for the device, and (if it's supported) insist that only
a particular drive letter be used. But I don't know how often that
solution is available.)

Failing that, I'd have to ask what might have changed on your
system between "it worked" and "it doesn't work"?
