It looks like the US version of the games was taken down. The Korean version works fine. You can download the Korean version of the games files from http://www.samsung.com/sec/support/download/supportDownDetail.do?group=&...

To install the games do the following:
1. Upgrade your firmware to 3.07
2. Open the P2 from your "My computer"
3. Extract the files to the data folder on the p2
4. Restart the p2

We recommend that you don't update your firmware right now since there are a bugs on it. We can't be held liable for anything you do to your p2.
