Absolutley do not listen to this A-hole! Start up your PS3, make sure your DLC content is still under the "Game Utility", and then check to make sure you have the latest software version by going to the update software option. If you don't have the latest software, download it, otherwise just start the game disc and you should see a message asking if you want to start BofGT or LandD DLC content. There is no logical reason for deleting your saved games that you worked so hard for. GREMLIN-"NO"SKILLZ should do something productive with his time like commit suicide!
I may be able to help. I downloaded and installed both DLCs, I started up GTA 4 and a message appeared on screen reading: "The Ballad of Gay Tony has been installed, would you like to play it?"(no mention of Lost and Damned, which I downloaded first...) I selected "no" because I haven't finished the Niko Bellic story yet, and would like to before starting another story. The game started again from the "The Cosins Bellic" mission (the first mission) and i was like "nooooo!", but i loaded my previous save, so no worries... anyway, pause the game, go to the "Game" section in the pause menu, select "New" and there will be a list like this:
Grand Theft Auto IV
The Lost and Damned
The Ballad of Gay Tony
Obviously you choose the one you want to play.
if this has not happened for you, then it looks like you just blew away a bunch of money.
i just downloaded both games and i cant seem to find them. i went to the start menu and then clicked on new game but nothing seems to pop up. can anybody help me please?
