Error 6 When Trying To Read Memory

[Chuuy]

For some reason, everytime I try to read memory, it always returns 0 with an @Error of 6. I'm using NomadMemory. Error 6 is:

6 = Failed to read from the specified process.

I have no idea what causes this problem. Here's the code I came up with. Also, I bypasses Hackshields hook, so the fact that it usually hooks ReadProcessMemory() shouldn't be a problem.

_MemoryOpen() as it's defined, expect a process identifier as opposed to a process name. So you need to call it like:

$ah_Handle = _MemoryOpen(ProcessExists("MapleStory.exe"))

You should also consider that if the memory is protected you'll need to use VirtualProtectEx() to change the specific page to be readable also, and not only write or execute for example.
