Authorize.net AIM & SIM issues - need help

[laurelsstitchery]

I'm using ZC 1.3.9d. When I setup the Authorize.net AIM module, the transaction appears to complete, but the charge never shows up at the Authorize website. When I setup the SIM module, I get this error "3|2|14|The referrer, relay response or receipt link URL is invalid.||P|0|||4.42|CC|auth_only||||||||||||||||||||||||||C32EE41F3058DCE376A4B 4E14F0F1076|||||||||||||||||||||||||||||||8a6toblh95u1olel91ch0em050". The charge goes through to their website though. It's 11:30PM and I've been working on this all afternoon, so I may be looking right at the problem. I just need someone to give me some hints on getting one of these to work. I would definitely prefer the AIM module, but at this point I'll take anything. FYI, I was having this exact same problem with the AIM module with my old OSCommerce cart, so maybe it's something I've screwed up. Any ideas?

I suggest double-checking all the settings you've configured in your Authorize.net account:
