Not able to play files after installing Creative MP

I installed Creative Media Source (the media player for my MP3 player) and now I'm not able to play files. I created a new tool with the path for the Creative player and added /ADD "%_path%" but didn't work.

I tried switching back to Windows Media player but it didn't work neither. I tried reinstalling and still can't play from MP3tag. What can I do to be able to play files from MP3tag?

/ADD "%_path%" is an example only for Winamp!
Please try just "%_path%"
You can also try to find the command line parameters of your programs in the manual/help or ask their support.
Or F4 key can also work.
