Lingrif; When I borked my first install of Vue 5, it turned out to be the detrius left behind from a hard drive failure that killed my Vue4VuePro drive (and being a typical windows program, Vue simply doesn't remove everything when it is uninstalled). I had to clean out everything from the system; app and Cow, registry top to bottom, and searching out the .eon files hidden here and there. The second install went just fine (well, except for the non functional RenderCow for Mover 5, and E-on is working on it). I'd uninstall, sweep the system beyond thorough, reboot, reinstall, and see what happens. If you get the same thing, E-on definitely needs to know...
