i dont have permission for that. is this because im using the free version? is there another way to fix it? whoops forgot to say im using the free demo version in my post

ive worked with videopad for a bit now, its a pretty good program. though, ive run into a problem. ive been editing a video for the past couple of days and everything went well. until i abandoned that project for a day or two to start and finish a different project. now while i open the first project, it freezes when i play it. either it goes out of sync while i play it and then freezes, it plays the video normally, the video freezes but the audio continues,causing videopad to freeze, or as soon as i hit play it freezes. anyone got any helpful advice on this? forgot to mention it in the original post, im using the free demo version. whoops
