eNom Reseller account - Bad User name or Password

I am using the Domain Mapping plugin, and I signed up to eNom through your link.

I have verified that my signup details are fully working, as I have logged into their site with them.

However when I try to login in WordPress admin Domain Mapping "Reseller Options", it says:

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

Bad User name or Password - 2

Please help?
