OK, I was just wondering how this exception could have been thrown from the CreateFromCER_PVK method, which is what I thought you said, but I see that it's thrown from the Connect method which makes a lot more sense. Unfortunately, this is not enough to allow me to solve the problem.

If it used to work, try to remember what could have changed since then:

* Has the certificate changed?* Has the code changed?* Have you got an old version of the code or certificate that you could try?* Did it work on the same machine?* Have you changed any Windows security settings?

Also, try to generate a new private key and certificate. If you still can't work it out, it'd be very useful if you could e-mail us the code segment causing the problem along with a private key and certificate that don't work (not your real ones of course). This page has instructions on e-mailing support.
