I was having a lot of problems. When I gave my 17-digit number, the site would find my account, but returned 0 games. When I created a personal url, it claimed my account did not exist.
In the end, it turned out to be a problem with Adblock. Disabling Adblock while viewing the page fixed this problem. Running total: $2127.56
The odd part of all this- I can still view my page if I enable Adblock again, though this isn't the first time this has happened recently.
Hopefully this helps someone else.
