Anyone have this issue before?  Thanks in advance for any assistance!

I've set everything up and am using Authorize.Net as my gateway.  I've entered my API, Key, and MD5 Hash.  I've set the Direct Resposnse to "Delimited" and "|" (Pipe) as the character (it defaulted to not delimited and I was getting the same problem- I was hoping chaning this would fix it).

I am using Paypal & CC: Test Mode.

When I submit my transaction, I get the following error:

The following error occurred while processing your credit card information:
Error code:2
Could not post to https://secure.authorize.net/gateway/transact.dll or response parse error. Error Message: System.Exception: Response verification failed. at CATALooK.CC.CheckValidation(String MerchantDefinedHash, String LoginID, String transactionID, String amount) at CATALooK.CC.ParseResponseString(String ResponseString) at CATALooK.CC.Charge()
