User not Permitted from this IP Address under Domain Mapping>Mapping Options>Account Credentia

I am using the Domain Mapping Plugin, in the Domain Mapping Plugin options it has found my IP adress as as I had Enom add this IP to my account but I am still getting an error message with the Domain Mapping Plugin under account credentials:

Looks like your credentials are invalid. Please, check the errors sent by eNom server:

User not permitted from this IP address - 4

I confirmed it with Enom and they sent me this message back:

Thank you for contacting us about your IP requirements. We have updated the IP address file for your account - you are all set.

So I am not sure why the plugin is saying that my IP address is not permitted when it is? Please help me figure this out.
