I've been trying to setup my subdomain for http://damian.nimeck.com/ to point to my tumblr blog. I've been able to successfully do this in the past with other domains not hosted by Dreamhost.
However, when I follow the instructions on the wiki, I get to my domain and get the following error when trying to set a A or CNAME record:
"You already have a record for this name. You can't have a CNAME and any other record on the same name."
When I try to edit that record that already exists, I cannot because its a "Non-editable DreamHost DNS records for damian.nimeck.com"
How/what do I need to do to be able to have damian.nimeck.com point to tumblr, but still keep the remaining sub-domains and regular domain (nimeck.com) on dreamhost?
