Your not the only one having this problem. It seems to be a problem with the site right now. I`m guessing we need to wait until Gamespot gets back from holiday and they will attempt to fix it then.

Its gotta be something on Gamespot`s end. Since its a holiday weekend its probably gonna be awhile till fixed.

Count me as another with this problem. I have a game on my now playing list that i finished a couple days ago and have been trying to move it to my collection and no go... just the white page and no change.
