I just downloaded my MH, and I checked the setup guide and changed the settings to auto reveal without ISO, etc. I intend to use it for closed realm MHing. What I do to set it up is:

I first start Sting's MH (without having installed the Plugin). I then start up my Diablo 2. I minimize Sting's, and then log in. Sting's recognizes my Diablo 2 but says "Can't create toolhelp32 snapshot of process 3732, err=5" In turn, I don't see a revealed map, and when I press "Reveal Act" it says something about not matching games?

So, how do I correct this issue?

for any of u that r getting this error also, I fixed it by downloading d2loader. I read something about the interaction between the two programs, but I thought that d2loader was a program bundled in the d2 installation packet. You actually have to dl the d2loader and "install" it into your d2 folder before sting's MH can work.

I just downloaded it too, I dont even have an .exe here ? :D
Or do I gotta winject some .dll ? help! WTB FAQ!

I am lacking in the required post count on this site to post a URL. I am sorry that I did not know this and I will make an effort to correct this.
