No hacks work

I'm not some noob new to hacking or anything, but I just can't figure out what's wrong. I'm running Windows 7 64 bit and any hack that I use doesn't work. I made sure I ran the Injector as administrator, and even if I minimize and manually inject nothing happens. I'm using Iamazn's Injector where you type the name of the process I put Engine. I've tried every numpad in-game and nothing happens, it's really pissing me off I haven't hacked on Combat Arms yet.
The hacks i tried are:
CA public v3 (Yes I did rename the .dll file)
NA pub by hesjan

Neither one of them seem to work. Please help.

Probably they both dont work for ur OS

or

try again with perx, or bombsaway's injector

they patched the hacks and plus you might need to try Engine.exe

It most likely is, if you have tried perX and several other injectors with the same result it is most likely your OS. Wait for new hacks to come out that say they are 64 bit compatible. Thats really the only advice i can give

I like using Finject and longevity's public hack. it should be the most stable hack out there so far
