Update: Ok, sorry for the panic. I found the file and restored it. I had deleted a portion of another file that was somehow connected to the finished product. I restored it from the recycle bin (thank goodness I didn’t empty the bin)and it gave me the file back.
But now, I burned it to a DVD and there’s no sound when I play it. So I’m rendering another way to see if it works.
“Supercharge this.”
