I think I messed up with some sort of utility programs and this has happened.

When ever i double click a media file it doesn't open. Just shows the busy sign for a sec and everything is gone. I have tried RIGHT CLICK and OPEN WITH but in vain. The only option now left is to open the media player first and then open the files from there.

And the PLAY ALL button in the music folder doesn't work too due to the same reason.

Any idea anyone?

I can't restore the system.
I have checked that all the media files are associated with the media player.

Thanks!
