I should be able to send you a test file tomorrow. We will try adding
that flag as well.

I'm happy to take a look at a file to see what exactly is wrong if
you're willing/able to send me one.  I'd need the key to decrypt it, so
either encrypt the test message to my key (99242560), or make a new key
for the purpose.

Most likely the problem you are having is that PGP version 6.5 is beyond
antique at this point.  You might try adding the "--pgp6" flag to your
gpg invocation, which enables some workarounds for various PGP 6-isms,
but basically the problem is that PGP 6.5 predates the standard that
GnuPG follows.
