I haven't used PGP 5.0, but does it give an error message when you try
to decrypt the file.  If it does, please let us know what the error
message is.  It could be helpful.

It wouldn't hurt to try.  As for the second question, I don't know.  I
don't have the knowledge or experience with these situations to answer that.

To the best of my knowledge, GnuPG can work with old versions of PGP
going back to PGP 2.x.  So I think that it may.  If you do use GnuPG to
decrypt your file, let us know whether it works or not.  And if it
doesn't work, post the error message so that we can further diagnose.
