Ok.
I'm not understanding what just happened.
So, i renamed my game folder from "GTA San Andreas full on Spanish" to "GTA" and it started magically. So, if someone looks this thread, and knows or can implement/add this to MTA nor MTADiag to solve this (like, check if root GTA dir has unknown/special characters, and rename it)
I have checked all advise about game crashing in this required post, before asking for help:
So, i can't find out why is crashing. While waiting I'm checking the pastebin's text to see what can be, help pls!
