I got CS6 a week ago and it's been working great. I've only done minor edits but it has worked fine. I just started editing a music video with lots of files. It works fine but randomly it started freezing when i was editing. The last couple times i has been when i clip on a file to preview before putting it on my timeline. Not sure why this would be happening. All the footage is from my Scarlet.
