Hello vivid,
You have to start ‘vorpX Control’ not ‘vorpX Config’. It displays a tray icon in your taskbar when it is running.
The config GUI isn’t that important currently. Almost all settings can be changed ingame after pressing [DEL].
However, there also is a potential solution for the config crash: Please delete/rename the following folder C:\Users\\AppData\Local\Oculus. This will most likely resolve the issue. The AppData directory might be hidden, you have to enable “Show hidden files” in Windows Explorer to see it.
