Hi, Is there anyway I can change the house I've chosen upon premium upgrade, it is not what I wanted. I want a 2 storey domain dwelling. Then I tried to switch it in settings and it wouldn't work?　It would change all the textures, and roofing but it wouldn't add a 2nd floor to the house?　PLEASE CHANGE ME　TO　A　SECOND　FLOORING　UNIT INSTEAD　ONE!　Thank you. Here is the unit I don't want... http://slurl.com/secondlife/Copal/44/128 Regards, SL　ID　-- Tycoonted
