Nextgen gallery breaks CSS

Hello, I got a problem with the Nextgen gallery, when I installed my theme everything works fine, but when I installed the plugin the css of my pages breaks. If I see the code, there is just missing a piece of code in the head section. I tried this also on my local server and there I just don’t have any problems. So I hope someobody know the solution for this.

Thanks!
