Thanks much for the update, I appreciate it. After reading through all of this I attempted injecting the file as well using remoteDLL, but I've experienced a problem:
I run remote DLL as said, then run Mabinogi. I "Select Process" to find client.exe but I can't find it in the list anywhere. Even when I hit mabinogi's start button it still can't find the client.exe.
Yes, I do run RemoteDLL as admin. When I open my regular OS' processes through task manager it DOES show client.exe ...
Sorry if I missed out on something.
