Hi. I am using Movie edit pro premium 2020. and it's a good programme when it works. For days on end I can proceed making a DVD or a Blu-ray video. However after this good run, for days on end the programme crashes or freezes every few minutes and working with it becomes impossible. then all of a sudden it starts working perfectly again. At first I thought it might be the new graphics card I had put in by an experienced friend. But Adobe CS6 on the same PC works perfectly with the same ghraphics card. I am 94 tears old and no longer understand the modern jargon so if anyone can help me please use plain language. Thank you.
