Leveling issue

Ive been browsing through these threads to find mod menus and hacks. I use to own a legit copy of the game but recently started having errors with creating and online profile so I switched to cracked version and sold my copy of WaW. I still have the online profile issue but I was just wondering if theres any level/prestige cheats or hacks that work with the cracked version its kinda boring doing several missions and my level staying at level 1. Ive already tried several tools on here but when i looked into it more it seems it will only work if u have an actual copy of the game. Ill buy the game again if there isnt anyway for the cracked version to allow me to level up in some way cause I dont even get challenges in this version of the game.
