I can't save any event in preferences

[PsyKOrion 0]

Hello

 

I tried to create some events but they don't be saved when I click on "save". I tried with AirVPN 2.6 on W8 and W7 and with installer or portable version. Same result. Is it possible to force it to add entries on xml file? (I think these parameters are saved on it). If yes, some one have an example?
Or if some one have another solution ?

 

Thanks
