Web address in use

Hello,
I had to reformat my server (I probably do that more often than I should) and that involved re-installing and re-configuring Subsonic. I'm trying to use the same xx.subsonic.org web address as before, but it's telling me it's 'in use'. I tried an even older one that I haven't used in more than a few months and it also says it's in use.
Is there a way to delete that record so I can re-use the web address? I hate to have to keep notifying my users of new URLs.
Thanks!
