8350i BB trouble with most games

Hey, can anyone help me with this problem: 1 out of 50 games work(kinda)on my BB.I get alot of "outa range", "file to large"(rare),"unexpected module something something" Ive done the boost swap with my BB(AWESOME)and have wi-fi throughout the house.ALL ringtones and wallpapers from here have worked excellent, its just that the games dont.Even when I search the site and ask for 8350i games, what it brings up mostly doesnt work.And even a few have crashed my phone.ssssooooo any advice?
