Payday : The Heist

Why are there no hacks out for the first payday game? i really need a hack to get all the upgrades on a certain class (mainly the technician) i have been using cheat engine and float values to complete the challenges that i get assigned and nutted the address down to the 1A28XXX or there about for challenges. can someone make a cheat table or something? i checked the cheat engine forums and there is nothing for Payday already.

TLDR; Class EXP hack (preferably cheat engine), Float values around the 1A28XXX address

i found out that A. the value i was pointing fingers at was only an address and that it changed and B. what i was looking for i could already do by myself because it was as simple as leveling up by hacking the float values that controlled the money i had (hurr durr gubbels, you should've known that) so basically i dun goof'd and i should probably lock the thread. sorry
