DragonMaster - your lack of response to peoples' suggestions, whether you understand them, or not, is impolite. I already know you often ignore things you don't understand, from your previous technical questions.
It is this impoliteness that will prevent most people from helping you.. how can they look at your progress when you simply don't respond to people's suggestions politely?
At this stage, normally, I would be reading this thread and seeing the person asking the questions' report on what they have tried, and what has come of it. Since I see none of this.. the help can only be surface level... I assume you have done a fresh install of San Andreas, prior to installing MTA:DM on it... without a fresh install, DM definitely won't work.
Please consider the time and effort people are putting into their suggestions when responding with feedback.
