Link Are you trying to use the trainer in multiplayer mode? Most trainers are made to work with SINGLE PLAYER MODE only. Here at Cheat Happens, we never intentionally create or post cheats that work in a multiplayer environment. Cheats (in our opinion) should only be used for single player modes and trying to use them in multiplayer will cause the cheats not to work and may possibly get you banned from that game's multiplayer servers.
I don't think that trainers would even function on browser games and even if they did Cheathappens doesn't make trainers for multi player based games as stated in the trainer troubleshooting menu.
