Delete any history of Rigs of Rods, like uninstalling it from the 'Add or Remove Programs' tab, and making sure that the RoR folders in "Your install directory here" are gone and all RoR folders in My Documents are also gone. Once that, just go to the Rigs of Rods homepage and download it and you should be set. If you have any more issues, please just ask.
