What "DaDoods" said is right. Try to right click it. If it still won't work just close the game(ALT + F4), because you have saved or maybe just wait a minute. ^^
I'm so sorry. I thought I had replied to you days ago, but I guess it didn't save or something. I tried right clicking, but that didn't work. Nothing works. It just acts like it's going to load and then sends me to that confirmation pop-up and I can't do anything else. I have to refresh the page just to try again. The buttons highlight when I mouse over them, so I know it isn't frozen or anything, but nothing happens when I click either one. So the whole order of events looks like this.
TRY TO LOAD THE GAME FROM THIS SCREEN
GAME ACTS LIKE IT'S LOADING
GAME SENDS ME TO THIS SCREEN WHERE I CAN'T PROGRESS ANY FURTHER
