eNom free account activation = `cURL error 28 error

I'm in the Domain Mapping plugin, under Reseller tab I select eNom, then I sign-up for a free eNom re-seller account link. I fill out the form and submit it but receive an error message. Not sure if it makes a difference but I'm developing the site locally.

cURL error 28: Operation timed out after 5000 milliseconds with 0 bytes received

Another question I have is that eNom seems to have a setup fee

but the setup screen from Domain Mapping plugin takes me to a signup form for a free account. I can't seem to find any information on the free version of eNom or what's the difference.
