Realplayer11 Gold

[Nehad elgmal]

finally i managed to install the realplayer11 on my ubuntu hardy heron i 
dowenloaded the rpm package from the web site and converted it to deb 
package with alien and installed it and start it normally but when i try 
to open any of my Mp3's it auto-closed without any apparent reason i 
also tried to make realplayer my default player but the same problem 
happened!!
