So first all of a sudden now when I click on itunes to open it i get a warning message saying that it is 'not a valid windows image' or something.

However after clicking ok, itunes opens. But what's that about??

Secondly and more importantly, itunes doesnt recognise CD's I put in to rip.
The computer recognises them because without itunes open it comes up with the options to play or view folder etc etc.

But itunes doesnt load up the audio CD list to import the songs... nothing happens.

So i can't put my CD's on to itunes right now!!

Please help, what is the solution?
