We recently fixed an issue that was causing consumers of the 2013-2014 version of the NHL GameCenter Live app to not be able to sign in. For users that were receiving an “error, restart application" message when trying to sign in, please delete the current app from your PS3 and re-download it from My Channels or the Hot PS3 Apps section of the PS Store.
Here are more in-depth instructions.
Go to the My Channels section and click on the NHL tile to download or go to the PS Store in the Hot PS3 Apps section.
After the download has been completed, the app will self-install.
You will be prompted to update the current app to version 4.00. Click “OK” to download the patch.
Next, you will see the NHL GameCenter Live subscriber sign-in screen.
If you have not signed up for a subscription, head over to www.nhl.com/ps3 .
If you already have a subscription, login with your username and password.
Once you have signed in, start watching and following your favorite teams.
