HELP! PAGE NOT FOUND.... EVER!

I've been unable to access my study notebook from my laptop for 5 months now, and I have no idea how to fix it. I get "Page Not Found" no matter how I sign in, what browser I use, or what computer. I can make notes in the scriptures from my android device (I have a Nexus 4) but cannot even get to that page from my laptop. I can access the ward directory though, and everything else. I have reason to believe it has something with the fact that I use my android device to change things... PLEASE HELP!!!!

This may be the same issue reported in the Page Not Found when thread.

Yes, and I've tried clearing the cookies, browsing history, different browsers, different computers, I just don't know what to do...
