For some reason, I can no longer use the program to render a video. I have already previously been able to use it, but yesterday it stopped working and I have no idea why. I haven't done anything different than usual. In fact, I literally rendered another video the same day, just hours earlier. That one worked just fine, even though it crashed like 4 times, but still got it done. Now it refuses to finish rendering. It get's to anywhere between 25-40% and just randomly freezes the rendering. I can still click on the different things in the window that shows the progress bar and has a few options, but in order to close out of the program, I HAVE to Ctrl+Alt+Del and use the task manager to close it. Using the X button in the top right, after it does this, does nothing. I can't figure out why I paid all that money for this program, just for it to not work after a couple of uses.
