Hey guys, I was surfing nexon forums the other day. I had no idea what to do so I followed a GM's advice. I uninstalled mabi completely first (even npkcmsvc), then downloaded a new fresh clean client with Mabinogi Download Manager and reinstalled (took about an hour x.x). After that I put in the mem patch and set the things I didn't need to 0 and patched it with jinsu-nogi a little later.
It might not work on the first launch and come up with the error message but works on the second launch for me. So now everytime I launch it twice, and it works for me. ^^ If it still comes up, I recommend doing what the beginning of this thread says and change every value to 0 except "Data Folder" and "Zoom".
I just wanted my zoom and non-laggy interface and font. =3=' Hackshield annoys me to no-end sometimes. As for the "server cannnot be reached" problem, I think that was because it was a Sunday (which tends to happen each Sunday for me).
Edit: Nvm about the server cannot be reached problem. I'm going to off/on my router to see if it helps. :\
