Mame videos not showing all of a sudden

[kaigator]

I double checked all the paths and it was working correctly before. I started adding N64 today and when I launched hyperspin to check my settings i moved over to MAME to show my kid a game we used to play. None of the videos were coming up for some reason. 

 

Anyone else seen this? 

 

I have double checked all settings, deleted paths-restarted computer and reset paths and nothing can't seem to get them to show.

If I go to folder and manually open vids they are fine

 

thanks any help would be great
