I'm using Magix movie edit pro plus 2021. It use to work perfectly fine with no issues. However i stopped using it for about a year and am now trying to use it once more and its pretty much unusable. When editing all the sounds are off, like you know how the sound is in a box when editing right? well once the orange line passes the box where the audio should stop it continues. Its the weirdest thing. And other times the quality is just super laggy, the video blinks and freezes, or sometimes the entire program stops and tries to load on certain parts of a video i'll be working on. I have no idea what's causing this, I updated my hard drive and my computer is pretty fast, every other app and game i run, runs fine. I've tried restarting my computer, updating the program, and more and nothing works. Any ideas on how i can fix this?
