82920 Authorizenet & Acct Manager!

I currently have the following: [login to view URL] setup to accept payment through PayPal and Authorizenet. All was working perfect for months, but now Authorizenet has changed to the following: "IF YOUR WEBSITE CONNECTS TO THE [login to view URL] PAYMENT GATEWAY VIA WEBLINK OR ADC RELAY RESPONSE AND YOU HAVE NOT SET A REFERRER URL ON YOUR ACCOUNT, ALL YOUR TRANSACTIONS WILL BE DECLINED" I can not set a NOT SET A REFERRER URL because i have other programs that will not process with Authorizenet if I do. What I need is the [login to view URL] script to communicate with authorizenet another way. The script is live and must be copied to another directory to be worked on. Do not work on live copy. Please do not bid if you are not familiar with neither. I really need this done timely and professional without disrupting any other features of the script. Thanks!
