Thanks for posting back with your results. The ssl how to that you used is for shared ssl. If the ssl domain for your store is the same as the regular domain you will not need this. This is the quote from the How To:
If your secure domain name is different to your regular domain name, you will need to follow these steps to make sure that when a customer makes a purchase through your site, they are transferred to the secure site automatically. 
I'm glad that the updated trigger is letting things work for you now, let us know if you have any further questions.
