We have discovered an issue where some users may experience the following problem during the download of new game updates when they have Update 1.02 installed.
Steps to reproduce:1．
When Gran Turismo 6 is launched while connected to PSN, a message will appear on screen informing the users that "the latest update data for this software has been found (Version X.XX)".
2．
Once accepted (by pressing the X button while selecting [OK]), a “Please wait...” message will be displayed. After a few seconds, the PlayStation®3 system will emit 3 acoustic signals and restarts automatically.
3．
At this point, some users may receive a message stating that the system was not shut down correctly last time. The system will ask then to perform a system file check and then the reboot is completed.
4.
Users will be prompted again to download the update, whether they received the message in step 3 or not.
Procedure to avoid this issue:To avoid this issue, please accept to download the Update by selecting [OK] within 2 seconds of its appearance on screen when prompted. This will update the game properly.
If you wait longer than 2 seconds, please decline the Update by pressing the Circle button when the message in step 1 is displayed, then select [Back] in the subsequent "Sign-In to PSN" screen. The game will start, quit the game using the PS button while in the [My Home] screen and follow the procedure described above.
Note:In step 3 you may also receive a message “Report this problem to Sony Computer Entertainment?”. You can select either [Yes] or [No] to proceed.
We deeply apologise for the inconvenience this issue may have caused.
