Computer crashed during update and now I can't access iTunes Store!

Hi! I was going to update my iTunes to the latest version, but my computer crashed halfway through. Ever since then, I can't access the iTunes store! I don't know whether trying to update it again would fix the issue?

Also, when choosing to update it brings me to the "download iTunes" page, it looks like the page you go to when you first download iTunes, and I don't want it to just download a new iTunes and not update my current one. I don't want it to affect my library.
