do I need to buy SEF Advance twice?

Hi Emir, I tried emailing you regarding adding a domain for my copy of SEF Advance but alas I've had no reply. I assume my email or your reply got lost somehow.

Anyway it says in your FAQ that you can point the SEF Advance to another url:
http://www.sakic.net/support/faq/sef_advance/#7

I appreciate that is says it must be uninstalled on the first url but I was hoping you'd allow some leeway whilst I move the site to the live server, in case anything goes wrong and it has to stay longer in development.

Please respond soon as they want the site launched on 19th or 20th Nov now. Otherwise I'll be forced to buy another copy, which I'm sure you wouldn't mind me doing 

Hello,

Sorry if I missed your mail (my server was down yesterday), please send it again and we will fix it.

Hi Emir, thanks for getting back to me on the forum. I did send you another email but it seems you haven't got that one either.

I've also sent you an sms but no reply yet.

The domain is propagating as I type, I've already paid twice now but haven't received anything.

Please help,

thanks
