I'm also having trouble with the stacks system. I was trying to edit the owned games stack and it won't load properly and it only shows 20 games, as a previous commenter said. On top of that it won't let me remove any games. I'd really like to use the stacks system, but I find it overly cumbersome at the moment and really slow, even if other stacks do load properly. On top of all that, I don't like having to click through to a game's page to rate it or unfollow it. It just seems like an outdated way of doing things.

I am also having the same problem and have yet to solve it. I am very dissatisfied with their customer service as they just sent me some pre-written stuff that didn't help at all. I just used my credit card on the network a month ago and now it says it's not valid. It did it to my other card as well.
