So I've been using it for a while now, but just the trial version. With FL trial version you could save projects but not reopen them, however, if instead you just completed the entire project without ever closing the program you could still export the project as an audio file. This is how I made all my other tracks, but obviously this is a cumbersome solution. Well today was the day where the windows update finally got me. Normally I leave a youtube video on loop while I go to sleep to stop windows from automatically updating thus restarting my laptop and deleting my project. Last night I didn't do that and I woke up to a restarted computer and the progress on my next track gone. Luckily I had saved the file but without actually owning FL I couldn't reopen it. In other news the track is going really well, I'm actually EQing stuff so expect something coming out soon, I think I'm gonna call it "Party Games". Cheers!
