Had to go back to Premiere CS6 because CC started crashing when viewing a clip in the Source window. Have to get work done so I went back to an older file in CS6. In CS6, I had two sequences I was working between and when I would copy clips from one to the other, I would lose audio on the sequence where the clips were going (video is viewble though). I could here it fine until I closed the project (after saving) and opened it later. The projects are identical, just one had a few tweaks to the edit. Same clips in the Bin. Any way of updating, relinking clips, fixing this issue?
