Origin Just Updated, but Won't Let Me IN

So, Origin is telling me it just went through an update but it, and I quote, "Whoops-the installer encountered an error. Please quit and restart the installation. You'll be up and running in no time." But when I closed Origin and came back, it still wasn't working, Every time I close Origin the only options it gives me is to stop the download or go back, but there is literally no options on the original message besides the link to this website. And when I hit stop download and try to go back in, it won't even let me on my game. I have no clue what to do or how to fix this. Another thing, it's also telling I'm on "offline mode" even though I have full bars of WiFi and when I try to go online, it tells me I can't because of the mandatory update.
