Parked domain name

[springbox99]

Hello,

I'm trying to add my domain name (springbox-airsoft.fr) in parked domains, but it seems you have a matter with names in ".fr". Everytime I try, I have this answer : «*Error from hooks wrapper: Domain action was not successfully completed [1]. Error: Error from park wrapper: Sorry, cannot determine nameserver IPs. Please make sure that the domain is registered with a valid domain registrar.*»
This answer does not appear with a domain name in ".com".
How can i solved the problem ?
Thank you

My registrar, contacted by telephone, confirmed that the problems I have to point my domain name to your servers come to you.
Please confirm me the server name : ns1.x10hosting.com 99.198.122.2 ns2.x10hosting.com 173.236.27.195
Can I just keep the server name of my registrar and change the ip address to point to your servers? And if so, with what ip address? one I found in the Advanced DNS Zone Editor?

Why can not I register a domain name ".fr"?

Thank you
