i purchased the vegas movie studio 14 and I am a new user of this product, i discovered i have to first convert all of my videos before uploading because vegas doesn't have the option to convert as far as i can tell. i used filmora in the past and this option was available on their product and cost less. the first time using vegas the screen showing my video disappeared and i can't get it back to the original viewing although i tried the view options under explorer and chose everything possible on the list and the screen does not look the same, i also tried the display option and tried defaulting back to the original setting and this did not work either. How do i get the viewing screen back on top of the display?
