Game has stopped running

DO NOT INSTALL! Downloading games illegally is (a) not supporting developers and (b) the people that crack games usually have hidden programs i.e keyloggers and such. I learnt this the hard way. Just buy a copy.

first is the memory full ,second are you set on auto save or not hope this helps

With most mmorpg's they have a different log in name, that once you use that you no longer have to enter in a cd key. can you skip past it or do a digital download from the internet to get the program on your pc?? You may try that otherwise you will have to contact Activision to verify that you have the right cd key and they will be able to advise you further from there.

go to the home screen and down load the most recent update

idk

go to home sccreen and install

your blu ray player is faulty you will have to contact playstation to repair it

finding your Key Code For COD4
running Windows operating systems and playing COD4 to find your CD Key.
Click on “Start” then “Run”
In the “Open” field enter “Regedit” and click on “OK”
Windows Registry Editor will open.
Expand in this order: “My Computer”, “HKEY_LOCAL_MACHINE”, “SOFTWARE”, “Activision”, and finally select “Call of Duty 4′
on the right side you will see “codkey”.

It should work after a long time if you traded because the settings are different on different disks
