I'm in the same boat as BlacksmithRon was. I have enabled the authorize SIM and disabled the offline credit card module now. When I do a test order and select credit card as the payment method, I then confirm my order and am taken to a page that says: "The following errors have occurred. (123) This account has not been given the permission(s) required for this request." I have been through my authorize.net account and don't see a place to take care of this.

Also, I do not have an SSL. Do I have to have one for this? Because I don't have one, I have not set up AIM. I was hoping that the credit card transaction could be handled securely offsite, through authorize.net.

In the mean time, I have re-enabled the offline cc processing so that the store is still functional.

Thanks so much for any help anyone can offer.
