Default [HELP] VPN problems

Whenever an app, e.g. Spotflux, tries yo connect to the vpn connection,the app closes. Without any error message, it just goes back to the homescreen. The moment it fc is the moment when the vpn dialog is supposed to open (that "do not trust this application.....") but obviously it doesn't. Unfortunately, I have no idea what might have caused this, because i just thought it was a problem of spotflux, but sadly it's the same for all vpn apps.
