GRID License Server Interface broken

Hi folks,

I’m setting up our lab for a GRID test drive and have a big problem with the Webinterface of the License Server.
It’s just looking like that:

I’ve tried the Installation on 3 different Systems (2 of them Windows Server 2008 R2 SP1, one Windows 7 Professional SP1) and had the same Problem.
Maybe it happens because of we’re sitting behind a http Proxy and the Tomcat tries to load some external content?

Thanks for the great hint, that worked!
I changed the prefeered language in Internet Explorer (Internet Options) from de-de to en and now it looks good.
