I was using FL Studio and while I was producing a beat, FL crashed in the process. When I re-opened the DAW,
It was like opening a fresh new installation of FL studio.
Everything was reset default settings, No third party drum kits were available in the browser section, Project files were not appearing in the recent project activity from the menu tab And the project that was opened was the factory project EDM type music that appears when you install at the studio for the first time.
It’s not fun to have to search again for all my drum kits and reinstall them in the file section from the options menu and is also not fun to have to create again all my settings that I had to improve my workflow. 
I have the license for the signature bundle installed on my MacBook Pro 2018... Any explanations on why this happened? And how can I prevent this from happening again?
