I've just installed it in my McBook Air, it worked for a few minutes and then stoped working. It doesn't play music anymore

Please provide some further information about what exactly isn’t working out any more
* Does the play button stop responding? Or does the platter still move?
* Is the problem due to your Output or can you still hear songs from other apps, such as iTunes?

I also has trouble with my music muting for no apparent reason. Disc continue running but audio stops for seconds and automatically started again. A real pain when people is dancing. I unnistaled the app to try again. Any other suggestion?
