Did you set up the sub-domain using the same username as for gorerle.com or did you create another username?
Try to create another subdomain such as example.gorerle.com and double check that the correct user is shown in the drop down next to ftp user/CGI user.
If that creates a sub domain okay I would send another support email to DreamHost, from the Support section, to check if the original sub-domain creation process was commenced but never completed. (It might be a good idea to send a fresh email anyway to sort out any issues in your account)
Sometimes you may see DreamHost staffers on IRC at irc.freenode.net in #dreamhost. They are normally chit-chatting games but you may get a word in if you are very quick!
Opinions are my own views, not DreamHosts’.
I am NOT a DreamHost employee OK!! :@
You act on my advice at your own risk!
