Im new to the whole asking the community thing, but i searched for about 2 hours and found nothing about this.    Anyways, i haven't used movie maker much, but i wanted to make a video for youtube where you put gunshots over music and sync it with the beat. It was working fine for about an hour but then randomly clips would start getting a yellow triangle on them and had an error message which i screenshotted below. i tried running it in compatibility mode, as an administrator, saving it in different places (on an ssd and hdd), i tried it with and without file preparation on and even restarted my computer but nothing works. the file works fine for the first 2 or 3 edits i make then it just does the yellow triangle thing on random parts. i also tried deleting clips but that doest work either.

im running windows 10, intel core I7 4790, gtx970 with latest drivers, 32 gigs of ram
