Hello Friend - as for your 80010514 problem... i had the same one with Batman AC, i tried to replace the Trophy.Dir file, but still no good - only black screen after telling me the game Can't load the trophy info\registration, the game will exit.
the best solution to you, is to redownload the games in different version - for example: instead of my Batman Ac - IMARS release, i downloaded the Batman AC - VIMITO release - works ace!
this is my best solution to you... as for games like sniper elite V2 - mine works excellent. try to download the Euro version of it.
MGS HD collection - i envy you :-||| i need to change my hard drive and put more space in order to play and understand your problem. sorry i can't help you in that matter.
