Authorize.Net Payment Issues

I am trying to get HotSpot and UserManager to work correctly and am having some issues. I have the HotSpot (which I can confirm works by creating an Unlimited account in UM) on a RB333 with v3.24 on it. For UM I’m using v4.9 with UM 4.9 and um-test 4.9 (wanted to check the new interface, which didn’t show up. But that is unimportant right now) running on an x86 box. I’ve set up UM according to the wiki for use with Authorize.Net and looked into Authorize.Net’s own faq about it and still am having troubles. I’ve looked for a while for answers and am not seeing anything wrong, and have had someone else’s eyes who is familiar with this to look at it, to no avail. Here is the issue:

I associate with the HotSpot and it gives me the HSLogin Page. From there I go to the sign up page (https://userman.domain.com/user?signup=hotspot) and I create the account I’m trying to test with. It sends me to the Authorize.Net page to fill in the card info. I fill it in, hit submit and it sends me to a page saying

"An error occured while trying to report this transaction to the merchant. An e-mail has been sent to the merchant informing them of the error. The following is the result of the attempt to charge your credit card.

This transaction has been approved.

It is advisable for you to contact the merchant to verify that you will receive the product or service."

I have dissected it according to the forums and Authorize.Net and have found nothing wrong. What I’d like to do is start from scratch with troubleshooting and see if someone else see’s my problem. I’ll get whatever config/screengrab we need. Lets start from the beginning.

Thanks in advance.
