I just got my copy of Disney Infinity today, and to my surprise, there are some issues with the gameplay. I know, because I spent hours playing it, then it froze up on me, and it said the data was corrupted. But there is a temporary fix to this. Direct advice from Avalanche/Disney is that you must uninstall the 1.01 patch ... Under games, scroll up to Game Data Utility there should be two Disney Infinity options. One is ~62 mb the other is ~2000MB. Delete the one that is 62mb and play offline. await notification of a new patch before going back online.
Just thought I should tell you all before you decide to take your copies back to the store out of frustration.
