Problem with GTA4

[Valore]

this may sound odd, but try disconnecting from PSN first then give it a try

though I would recommend going this route, here are some methods that may fix the problem for you, but most likely will not help:


1) Delete the game's install data. This is done via the PS3 options. Scroll along the cross media bar until you reach the 'Game' tab, now scroll up / down the list until you reach the 'Game Data Utility' Enter this and locate the GTA IV option. Highlight this and press triangle once, from the menu select Delete. This will delete the game's install information.

2) Delete the game's save files. To delete any save files you will need to do the following. Scroll along the cross media bar until you reach the 'Game' tab, now scroll up / down the list until you reach the 'Save Data Utility' Enter this and locate the GTA IV option. Highlight this and press triangle once, and from the context menu select Delete.

3) Disable your Internet connectivity for the PS3. To do this scroll along the cross media bar until you reach the 'Settings' tab, now scroll up / down the list until you reach the 'Network Settings'. Now scroll down to the Internet connection option and press x, now select the disable option. Once this has been done unplug the ethernet cable if you are connecting to the Internet if using this.
