itunes 12.2 won't open
Hi,
I currently installed itunes ver. 12.2 on my macbook pro:
13 inch, Early 2011
2.3 GHz Intel Core i5
4 GB 1333 MHz DDR3
OSX Yosemite 10.10.3
When I click the itunes shorcut on my dock or play any song on the folder the application is unresponsive and will not open.
I restarted the computer and it still is unresponsive.
Please advise,
Thanks
MacBook Pro, OS X Yosemite (10.10.3)
