I don't understand the language, but I know the console wrapper that is built into Serviio won't work on any version of Windows older than Windows 7. This could be the issue with Server 2008.
However, you should be able to open the console using either Internet Explorer or the Chrome you have installed on the server. Just open
http://localhost:23423/console and it should work.
If I am misunderstanding the problem, I apologize.
