I have FL 20 on Windows. everytime I open Vital and browse presets, it crashed my project file. Any help?
The only help I can give is to say that Vital does not crash FL Studio 20 in Windows 10 on two different systems here. Are you using Windows 10 ?
Are you using the VST 2 or VST 3 version ? I would recommend using the VST 2 version for the time being.
Also if you could report the issue at the Image-Line forums they may be able to shed some light on the situation.
