my amarok is corrupted ,insatlled via yum, how can i repair
 

my amarok is corrupted . it shows thesome of the songs which are avilabe in a colour which signifys the file is un avilable whhich is not the fact. when i click on the song it adds duplicat entry and plays that one

i insatlled it via yum and hope complete uninstalltion and reinstalltion may help

how can i repair

I'd try deleting all the song lists first, re-creating them from the start and checking out that no locale is causing this. I've seen Amarok do idiotic tricks when facing some non-standard characters in file names or id tags, and wouldn't be surprised if that was the problem.

Anyway, if you want to delete it, just read yum's manual and see how you can remove (or better yet, purge) software. Then just
read the manual page and see how you remove stuff
if that was the case; this is just my guess. Man-page tells you more about removing/purging software.
