FTB app wont open minecraft

[Kezeriyon]

Hi,

I've installed the FTB app and it absolutely will not open Minecraft when clicking play, I have tried reinstalling it and reinstalling it in a different place, in total it worked once when I first installed it, can anyone shed some light on this?

Thanks

have you set the instance directory in the settings? also check if there is maybe a java process open that stucks and which you should close first.
