Hey Hibblet,
may I ask which browser you're using? Naturally, the newest versions of Internet Explorer or Mozilla is to recommend, along with an updated version of Flash. Google's new browser, Chrome is also known to do quite well with war-europe.
We're well aware that some are having difficulties browsing our website and it's something we're looking at improving. For now, trying different browsers, clearing browser cache and pressing F5 a few times is the way to go. I've sometimes had problems myself but I've never been completely unable to use the webpage.
Good luck!
