Actually, I have contacted Ken Ramirez in the past about the gateway and he has been kind enough to help. This time it is being used on a new site with a new nBill license. I am assuming he is just too busy to respond, since it has been a couple of days. I actually looked back through old trouble tickets of mine and realized that we had the same issue before, but you commented out a line somewhere that basically canceled the Hash check. That would be a satisfactory solution for me until I can get the problem resolved.
If you would just tell me what file and line# to comment out, I can do that myself. Or I will raise the ticket if that is better!
Thanks for your help! You are always very helpful and prompt and it is much appreciated!
