Well, I just purchased VideoPad 6.10 a couple of weeks ago and I am having the same problem. I am running Windows 10 on a Dell Laptop Intel i77500u 8GB, 64-bit 2.7 2.9GHz. Initially it just shut down when I was trying to save my full project which included multiple shorter videos from about 50-plus MB to over 100MB. Now, even when I am trying to make adjustments to the smaller video segments the machine is shutting down. I need to finalize this project ASAP for a presentation. Can anyone offer advice? This thread was a couple years ago and different VideoPad version. Same issue though. Thanks. T. A.
