itunes shuts down when I start up itunes match
I've had itunes match on my computer for some time and I'm nearly finsihed the process of matching all my songs, with only about 300 left to be uploaded out of a total of 8000+. In the past few weeks, when I start up itunes on my computer I get the message "Please sign in again". When I sign in again and start up itunes match, I get the message "itunes has stopped working" and the program shuts down. itunes itself works fine, but the match function appears to have gone haywire. Help!
