My iTunes Is Weird Tonight

I was trying to open it and it asked me to choose a library. I've never done that before. So I don't know what might be wrong.

Then I chose the only one there was and it froze trying to show me the album covers. So I had to do a hard shut off of it and now I'm trying to reopen it.

I hope there's not a big problem. I hate starting over on this stuff. I did have to start over with a fresh library three or four weeks ago, thanks to a problem that was my fault.

UPDATE: It seemed to work OK the second time. But, LOL, it's prompting me for yet another iTunes update! Can't they get it the way it should be and leave it alone for a few weeks!? Good grief. We shouldn't have to suffer all these long, dreary updates all the time!
