Stronghold Crusader

I'm having a hard time with this,I have already conquered this game before but I decided to play it again and unfortunately I lost the map that your given towards the end of the game.I recently downloaded the trainer download from cheats.com and placed it in the directory but I dont know how to get the cheats to work.All I want to do is unlock all the levels of the game so I can go straight to the point I was at before I lost the map.Can anyone help me use the trainer or does anyone know of a cheat I can use to unlock all levels of this pc game?
Thanks for any help you can give me!!

Ive played through pretty much the whole game the campaign most of the crusader trail and the historical battles and i don't recall any secret maps and i never bother with cheats (it is a Rts but it does sound pretty cool) so if u feel the urge to play the game buy the original stronghold great campaign and it has a great siege game type or for something newer stronghold 2 which is actually pretty good . stronghold the original one can be found from any used store that sells games gaming stores that sell games are the best (Eb doesn't carry them in stock anymore and i don't know if they carry stronghold 2 they should though but if not there is stronghold legends many options to choose from ) there pretty cheap especially the original which i say is the best one (sorry bout so much info that doesnt seem to be oh so helpful but its better then no requests)
