Well basically it's what the title says it is, I start MTA and instantly I get a crash message, telling me to restart MTA countless times. And yes, MTA was working fine a few hours ago. 
What i have tried to solve it: 
- Reinstalling GTA / MTA 
- Using a backup clean GTA3.IMG 
- Attempted to google a few clues. 
Here is what the crash message basically said:
