Got the same problem here, as well. I also cannot access certain pages on the site, like download pages and the "Trainers" sections in the search results.
Maybe It's just an overall site problem? Cause i saw the site had a downtime two days ago or so, maybe something to do with that? I'd also download my offline key, but since everytime i try and access any download page i get the "Oops your page doesn't exist" error, I'm in the same boat.
