Update Easydiscuss and keep the same theme.

Hi there we are using the EasyDiscuss 2.0.3945 and we starting the update to the the latest easydiscuss version, so we begin this process in a local installation, but we need to keep the same theme we are using right now here http://tutorialmaster.com.br/forum.html, but we did not find it in the new version. Can you give any advice on that?

With best regards
