Mullvad vpn on openvpn

I know that this isn't really the forum for this question,but I thought I'd ask anyway. I'm trying to configure Mullvad in openvpn, I entered my account number number and password everything goes fine but i get an error message saying "cannot resolve host address,name or server not known" I know that this forum isn't for this subject but I'm a new member on the openvpn forum and can't create new threads yet. I'm just wondering if any Gurus heremight be able to help. Thanks.
