Internet Radio not working on N78

I have problem with Internet radio application on Nokia N78, it displays "Feature not supported". This phone has excellent sound output and I was using a lot this application but I don't know how this application is not working anymore. I tried so many radio internet applications for this phone but none of them was working, possibly something went wrong with the phone SW. I also tried to update the SW but it says "no updates available"
Anybody knows how to recover internet radio application or had some similar problem?!
Thanks
