Stops working After 1 Drag

So I use Scaler 2 in FL Studio and after I use the midi capture once and drag the midi out it doesn’t let me use that function again. If I try to close scaler 2 or reload it FL studio crashes and when I restart it if I changed any setting (tool bar, sound device, so on) they all get reset.

Anyone else having this issue? I love the plugin in but it’s pretty useless if I can only use it once.
