Joomla 3.0 Template doesn't load in this Version of Joomla

Hi,

I'm trying to use this template in a Joomla 3.0 but the template doesn't load as a Template, simply it doesn't anything.

I've bought this for a Joomla 2.5 Site and it works great, but now I'm planning to migrate to the new Joomla 3.0.

What should I do!?

Thanks in advance.
