umm did you try to run? If you run, you SHOULD notice a bit of speed increase from the previous run(w/o speedhack). Remember... Speedhack is not ultra fast dragon ball Z speed. For me... 111/101 is just a slight increase of speed. But i tested different values.. it became faster. Try that.
alright the only problems you should be having with mhs speedhack is either A. you didnt attach it to engine.exe or B. you didnt hit the START SPEED HACK button. If you did both of these, reinstall, reboot ect ect.
