Launcher won't run any modpacks

[TrakerTak]

When I try to launch a modpack it loads it up and everything, the launcher minimizes...but then it pops back up like I never tried to launch anything?

I really only downloaded the launcher for B-Team anymore, only the vanilla works, I even downloaded the new beta launcher you guys just put out but even IT has the same issue.
