Error 500 in media manager and no images in zoomer

Hello,

I just install from hotstart 1.5 Hot Events and I can't get images in hot zoomer module showing.

Besides, if I try to see media manager from back end I get: 500 - An error has occurred. Layout "thumbs" not found or Layout "details" not found it I select the details layout.
