I can't download my games?

So, i tried downloading a game (LEGO Star Wars 2 DS), but when i did, nothing happened. The thing showing the page was loading didn't stop at all. I tried downloading a different game but the screen turned into a message saying something along the lines of "Wait for your download to end before downloading something else. If you are here by accident, we are sorry. We're trying something new.", which really weirded me out, since this never happened before. I hope you can fix this, because this is the only good site for downloading games that i know of.
