I have a blog at http://www.thewalkntalk.com which I currently use on a self-hosted JustHost server. Before I was on a JustHost, I had a wordpress.com account and that is how I created this domain. I have deleted that wordpress.com account now because I have not used it in a while, but today I got an error saying “Warning! Domain mapping upgrade for this domain not found.”. Long story short, I now need to find a way to change my nameservers back to JustHost to get my site up and running again. I tried calling Wild West Domains (they own this domain) and they asked me for my customer #, which I do not have. Please advise what I can do to fix this.
