Having trouble with iMovie 06 themes

I have IMovie 06 and when I click on the themes section there is nothing there at all except a box with a play button on it, but not the normal list of themes...
Anyone?

well i figured it out... i drug all my application support to an external to save room. so the themes were not on my internal HD... i drug them back over but they ended up in clips and not themes and i don't really know how to get them in themes... idvd is messed up too now... man, i screwed up... don't drag ilife stuff to externals! not sure how to start all over now...
