Same thing (almost):
I am developing on localhost and when ordering VM Invoice I did not know what to put into the "Site URL" and "Testing URL" fields and perhaps naively and not knowing better I just entered "Testing URL". The case of localhost is not mentioned in the ordering page of ARTIO. I now assume that at least the Testing URL should have been filled with "localhost/<myJoomlaname>". Do I now really have to pay an additional fee just to get this corrected and get the latest upgrade?
PS. In the meantime I have acquired a registered domain name, but it is not yet online and I am still working on localhost during development phase.
