Do i dont think i did uninstall any old vers. Fuu what can i do if its that??
Question, were you trying to edit the config.xml file that is in the program directory of the hex editor? If that XML gets corrupt the software will crash. Like Jets said, try a re-install and update us here at the forums. The software uses the microsoft .NET framework. Have you installed any other new software on your computer lately (or uninstalled?) that might've made changes to the .net framework?
