UCC SSL Certificate troubleshooting

I bought multi-domain (UCC) certificate from GODADDY and set it up for 2 different websites (not subdomains). Both websites reside on the same server with same IP. The certificate works fine for the first website (primary domain [login to view URL]), but for the second website ([login to view URL]) as soon as I hit https page it redirects to https page on the first website. According to tech. support from Godaddy, this certificate is properly configured and installed. They (Godaddy) claim that something is wrong with my IIS settings on the Server, or with my scripting. Scripting should not be a problem as those are 2 different sites from different clients and they do not have anything to do with each other, except of being bound by the same certificate. This is how you may replicate a problem: 1 Browse to item page http://pets-crematory/[login to view URL] 2. Click "add to cart", then enter your zipcode and click "recalculate". Shipping cost will be calculated. 3. Click "Checkout" (not Google checkout) 4. "This Connection is Untrusted" message will pop up. 5. If you accept it then it will redirect to a shopping cart of a primary domain ([login to view URL]) It sounds to me like an installation or settings issue and should be easy fix for someone who knows what he/she is doing (not me). I assume that $50 should be a reasonable reward. I am new to this site, so let me know what other information I should provide to solve the problem
