Theme Not Available on Blog

Hi, I recently purchased and was provided the theme installation by members of your team. I somehow have two wordpress sites and was able to successfully choose a theme and customize it perfectly!! One blog address has the http://www.xxx.wordpress.com and the other, and one I want to use, is http://www.xxx.com . I chose the Fictive theme on the .wordpress.com and really enjoy the layout. When I realized that I wanted all on the non wordpress.com site, I am not able to use the same theme. It only allows me options to change colors without the layout themes available. I can share the log in info if that helps clarify as it would seem I could use the same theme on both? Thanks in advance
