Hm.. Did you start it through the Patcher, or did you just do Element.exe? Because it may need patching. If not, it may be a problem with RAM or visuals? I'm not exactly sure. If you want a truly knowledgeable answer, from a guy who probably knows exactly what you're dealing with. MageTank will probably respond eventually.
But for my advice: Check to see if you're up to date on patches, or restart your computer, maybe clear out some of the files that are cluttering up your computer.
