Authorize.Net AIM problems

[fright-rags]

I searched the boards for an answer to this but couldn't find the exact problem...maybe I overlooked something. Anyway, here's the deal:

As of this afternoon my site stopped taking credit card orders. The error message returned was "You transaction cannot be completes for this reason. Please correct your infomation and try again." I have not touched anything on the site so I'm not sure what is going on. Here's what I did to try and fix it:

1. Uninstall module, then reinstall - NOT FIXED
2. Complete test transaction on Authorize.net terminal - WORKED
3. Searched forums...only thing I found was to change the Deliminated Response to "YES", Default Separator to ",(comma)", andf Field Encapsulation Character to "none" - DID THAT
3. Installed just Authorize.net module (NOT AIM) - WORKED
4. Uninstalled that module and tried Authorize.net AIM again - STILL DOESN'T WORK
5. Called Authorize.net and they said it had to do with Zen-Cart. So I reinstalled the plain old Authorize.net for now so I could accept transactions while I figure this out.

Why would one work and not the other? I'd much rather use AIM if possible as it allows for greater customization...and yes, I have a SSL certificate. Like I said, everythign was working find until this afternoon. Any ideas?

I would upgrade to v1.3.7 with the PayPal Patch at:

And the USPS update for the May 14th changes:

Then ensure that you have cURL installed on your server and that you have your secure pages working properly ...

Thanks. I had already upgraded the USPS patch and the secure pages are working fine. Orders have been coming in via PayPal, and as stated before, I can process credit cards using Authorize.Net...just not the AIM version. And even though I know the move to 1.3.7 is inevitable, I'd like to see about fixing this version first. Is there any way to do this? Why would it "break" to begin with when it was working properly before??

First questions are:

1 do you have cURL installed right

2 do you have a secure checkout

[fright-rags]

1. What is cURL? Not sure if it's installed or not.

2. Yes, the checkout is secure.

Ask your hosting site if you have cURL enabled on your site and if it is working correctly ...

authorizenet_aim requires cURL in order to function correctly ...

[fright-rags]

I'll definitely ask...however, it was working correctly, now it is not. And I haven't changed a thing. So regardless of the cURL being installed, things were fine until yesterday. Any reason why that is?

[fright-rags]

Yes, cURL is installed. What now?

Did you host recently make any changes on the server that would affect cURL or any communication ports?

[fright-rags]

Not that I'm aware of...I've contacted them and no changes have been made.
