Just chatted with Sony support since I lost the store software when downloading the update. My vista system hangs giving error code 1935 and the tech said to wait until tonight or in the morning to download the update when the rollout is complete. The system is still updating....so I will wait. Also said to delete all older version of the bookstore.
Now the real question, why make somthing available when it is not completely ready? Way to go SONY!
