Question because I am dumb when it comes to computers and such

So I have been trying to get to pinterst on my computer and I can't access the site.  I could yesterday.  I use google chrome.  It says connecting and all that stuff, and then I get a blank screen with the pinterst logo on the tab thing.  When I click the pinit on a pic, it doesn't come up either.  However, if I click the pin it button on my tool bar, that works, but then I can't pin the pins.

 

Oh good that sounds so stupid.

 

However, I can ask the site via the app on my Ipod.  Is anyone else having trouble?  Is there a magic button or something?
