For the knowledge or everyone:
I called my bank asking about why I couldn't pay with my MasterCard. They looked up in the system, and there where in fact two authorization requests from eNom when I tried to pay, and they where rejected by my bank because the authorization requests either didn't include the CVC2 code or had a wrong CVC2 code (she couldn't tell me which of these two problems it was, but definitively the problem was with CVC2).
I for sure entered to right CVC2 code for the card, especially that I tried twice, and I use the card on many other websites and it worked, so eNom or its payment processor must have not transmitted the CVC2 to MasterCard correctly or not transmitted it at all.
red123: when you finally succeeded to make this payment, was it a Visa or MasterCard?
Maybe they have a problem with their transmission of auth data to one of these networks, but not the other.
I actually funded the account through pay pal.
At first, I tried just my card which is a Visa. I also know I put in the right information but it gave me the error "problem with pre authorization" or something to that effect. It did not go through..
I did pay with the same visa, just through pay pal, which I had to add a automatic payment contract and then delete it and cancel it from within pay pal before I signed out.
I am not sure what the issue was, but the information was already filled in for the account owner so they might just not accept CCs is other names/addresses, not sure, I know that some are more strict than others.
