You need to understand that making music is one hell of a process for the computer, reason being that first off it uses a LOT of the computer’s resources, and secondly, since you’re using so many different audio files and audio VSTs from different sources and software developers in FL Studio, it’s so easy for compatibility problems to show up. Your project file simply got corrupted. Finance house personal loan It happens. Best way to avoid it would probably be to make sure you have backup enabled. Go to Options > File Settings and under ‘Backup’ choose an Autosave option. I set it so that it saves every 5 minutes and before risky operations but you can set it to whatever you want. You see that ‘Backup’ folder in your browser on the left? Every time it autosaves, it throws the save file into that Backup folder.
