No problem. The domain I set up with co.cc is cincinnatusjd.co.cc
I don't have a heliohost username yet, because I'm getting the error during sign-up. During sign-up, I select the "Other" option, and I have tried using http://cincinnatusjd.co.cc, http://www.cincinnatusjd.co.cc, www.cincinnatusjd.co.cc, and cincinnatusjd.co.cc, and I always get the same result. After I click submit, I get the following result:
We're sorry, but that is an invalid domain. Please go back and correct it.
Thanks for all of the help so far!
+EDIT+
Here is a screenshot of the server information on the domain:
