Do you have a fixed number of Vegas Pro Move(files) imports? When you open this file in a new window, it opens properly during operation, but when the number of mov files increases, you get the mov file, but you go offline. Not every time. It works normally three or four times, but suddenly goes offline and reruns, and the operation stops. I tried formatting yesterday, but there was no result. However, if you open a movie in a new window, it opens well. As the number increases, it suddenly goes down.
