Q: iTunes won't open on my pc - june 2015

June 30, 2015. Last night iTunes was working on my Windows 7 PC. I had opened it up, listened to my K-Pop radio station at dinner and the world was wonderful. I bought a couple of songs successfully. I attempt to open up iTunes today and no go. No luck. I open my Windows Task Manager and see it attempting to open up but nothing, no visual indication that the iTunes is close to deciding to open up. My iPhone still has iTunes and I bought the few songs I was looking to purchase today but through the day - no iTunes at all. My internet connection is fine, I ran Spybot and Malwarebytes and my BitDefender shows nothing going wrong. NO changes to computer otherwise. What's up with all of this?
