This crash clearly shouldn’t happen, but it can only affect native 64bit applications. So far almost all games also have a 32bit executable, it’s worth a try to check whether these work.
Other than that, please try to temporarily disable anything that might interfere with vorpX. This might be a virus scanner, a chat program that can display content over games, or a special display driver for example. If you have trouble starting anything, it is very likely that something on your system interferes with vorpX.
If you continue to have problems after checking this, please write a mail with some basic information about your system (processor, graphics card etc.) and – most importantly – a list with the games you tried to support |at| vorpx com for individual trouble shooting.
