Hi! I'm currently using the free version with the hope of upgrading as the programme looks as though it will have everything I would ever need, but I can't somehow make things work the way I want them to. At the moment, I am trying to do something so simple that you will probably all laugh at my incompetence, but I've been trying all afternoon with no luck. All I'm trying to do is create a new file with a clip of one track (which I have already trimmed to my liking) to lead into a different tack which is played in full. I can't however seem to be able to paste/copy anything from the orginal onto the new file ('untitiled') though I have managed to cut sections. Could this be because I am using the free version and this is a function that is not yet activated or am I doing something really silly wrong?
