First time I've ever ran into a problem with PD 12 on my new machine. I just encountered an issue today that when I was trying to put a mp4 supported file format onto the timeline, I get a Media Source Error(see below screenshot). This never happened before. PD 12 used to allow me to put mp4s on the timeline. Please help!

Thanks so much!
