iTunes notworking

Hi all

When I open iTunes, I get a message that a movie I had rented had expired and was deleted.

After I click ok on this, a dialogue box appears which continuously flashes; I can cannot close it or get past it, hence iTunes is no longer working.

A picture of this box is below; the word "password" keeps flashing in the box, which makes me think it is the log in for the store.

I have tried deleting and reinstalling iTunes, but the same problem keeps happening.

Any ideas?
