You tried higher levels? I don't remember much from when I used to use Cheat Engine back in the day, but I do remember there being levels to the pointer scanner. Depending on the level it scanned deeper and deeper for pointers offsets equal to the level you picked. 3 Levels = Base + 3 Offsets? Something like that, I don't remember the specifics.
I recommend you try a hacked client though. They're always better
