Do you save your progress often? If your computer turns off randomly every now and then, make sure to save files every so often.
Try to make it a habit, otherwise you'll lose work repeatedly lol. For example, before I go to sleep I would always save a file for tracks that I was working on earlier, just in case I open the computer and the tabs reload or close.
Ill tell ya what, ive loved watching people over the years improve so much, you guys are killing it! Keep up the good work all
