Oscommerce ssl cert troubleshoot and correction

Im trying to get a new install of os commerce up and running. and the cart is just about [login to view URL] last hurdle is ssl Im in the process of setting up my cart ...and ... Im moving hosting......and dumping an x-cart to move to oscommerce the actual domain of my existing site dns still points to my old server( [login to view URL] ) untill everything is done on the new server..... basically the cart is other than a couple of tweaks finished..except for ssl.. i have been installing and editing the site and cart on the new host via a modified hosts file on my pc i have set up my secure domain as a subdomain ([login to view URL]) and im using a modified "A" record on the subdomain so it resolves properly...since that same subdomain also exists on my old hosting... the new A record dns is resolving correctly and pointing [login to view URL] to my new hosting... if i go to my [login to view URL] domain its working...no errors ect...it is configured correctly itself... and it shows the lock, and i have a modified [login to view URL] file sitting in the secure directory to verify its the correct dns the relivent portion of my catalog/[login to view URL] file is pasted below... (the ssl cert is set up without the www..so the [login to view URL] is correct) here is the problem..... whenever i get to the point where i hit the checkout button i get [login to view URL] a 404 error Not Found The requested URL /ab_cart/catalog/[login to view URL] was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. I need this resolved and btw its an adult site...so if you decide you want to see for yourself....heads up and regardless without modifying your hosts file you wont be in the right place anyway... if you cant deal with that dont waste my time or yours
