Problem after installation Synology DS212

Hi there,

I installed Serviio on DS212, I can see Serviio on PS3. But after log in my Synology and lunch Serviio I get something like my picture showed.
My skills are not perfect but I can find mistake during installation process with your little help I think.
I rebooted station few times and nothing, once I choose Java 6 next time Java 7

Is anybody help me?

Thx
Tomasz
