I'm afraid this error is an indication of an actual bug in either
the server or the client; it's reasonably commonplace for the
provided host key not to match the one you have stored in the
registry, but for the provided host key and the provided _signature_
not to match is pretty bad.

I don't suppose (out of sheer desperate hope) you were using the
Unix port of PuTTY? I fixed a bignum bug in that the other day which
might reasonably have caused this symptom.

If not, I'm afraid you probably do need to mail the PuTTY team.
Please supply an SSH packet log of a failing connection. (This can't
risk giving away vital information if it fails before you
authenticate.)
