Certificate Expired Problems

Someone reported a problem that when installing getting a "Certificate Expired" message. I thnk this is because it's one year since I did the self signing on the SIS, and self signing lasts only one year.

I'll upload a re-signed version later, but in the meantime anybody who experiences might try just setting the clock back a few months, and see if the install can succeed. You can reset the clock back to the correct date after install.
