Technical Help

[Kezza15]

i have been playing through some of my games to collect trophies which i have missed, but when playing through, some of the trophies are not registering on my game, only 2 games are doing this and they are guitar hero warriors of rock, and assassins creed brotherhood
i dont understand why it will not show that i have earned the trophy, i have done what is neccasary for them, but no trophy and nothing happens
please give me some feedback on this

Are you still getting trophies on other games?
It might be worthwhile to visit one of the various PS3trophies websites to make sure you're fulfilling the exact criteria to gain the trophy.
Some trophies may be glitched (not sure if it applies to the two games mentioned as never played them before), but details of this will usually be shown on the 'specialist' trophy sites as well.

i have done exactly what is needed to get the trophies, seen videos of it done on youtube etc, even some of the simple ones like 'collect....' or 'find....' dont work on assassins creed
but it seems to be that it is just certain trophies which the game doesnt register, playing through the story on AC brotherhood i get the storyline trophies just fine
i dont know whats happened :/

Have you tried syncing your trophies (and being online)

[Kezza15]

yeah, i even done what was needed to get the trophy at least 2-3 times but still nothing happens

Try deleting the game data for those games and trying again.
