Even when I try it in an empty project, this error occurs. I also noticed that I can't drop Soundfonts in the sequencer. This must be done in an other way: First I have to load the Fruity SF-player, and than I have to load the SF in the player.
This also works with AC's. When I add an Auto Clip and then assign the knob to the AC it works perfect.
Reinstalling FL works fine for empty projects (and other projects as far I've tested it). But when I try to create an AC in the project I'm working on, the error occurs again. And then, I can't create AC's in empty projects anymore.
How can I solve this?
