I've never had a problem with itunes in the past.

all of a sudden today after downloading a song when itunes went to launch itself and up comes the message:

"The itunes music library file cannot be read because it does not appear to be a valid library file."

what can I do?

It is the latest version of itunes
Im using 10.2.8 on a g4

I deleted the itunes library file

opened it up and re-added all of my songs. Is that the only solution. I dont want this to keep happening.
