Hi Nash,
In order for the Answers Community to offer useful suggestions you'll need to provide more information such as ...
- What kind of tracks, audio or midi? (they both output audio)
- What operating system you are using.
- Have you tried (for example if audio clips) moving the clips to another track to see if they play?
If you make a new question about this kind of issue please provide a little more information and if possible also include an image so that the Answers Community can have a better understanding of the question. Otherwise, the question will mostly be remain unanswered.
