iTunes corrupt file problem

[seb_ncfc]

Hi and sorry to bother you
I dont currently own an iPod but am soon to own a mini.

Ive been using iTunes for quite some time now and ive just encountered a
problem im hoping someone can plz help me with...

At a random time my iTunes started playing up, i was using it normally one
day, closed it, tried to open it back up later on and it came up with a msg
saying

<:iTunes.exe - corrupt file

The file directory(shows file location)is corrupt and unreadable. Please run
the chkdsk utility

and when i do open iTunes theres is none of my music there. i know where to
locate it, but everytime i put it back on iTunes, i close iTunes and when i open
it again, same thing happens.

thanks for your time, i really hope someone can relate to this..
