Need help fixing saves (Grand Theft Auto: San Andreas)

Faced with the problem that my save stopped working. For me this is a huge problem, since I'm going through GTA:SA in manual at 100%. Pass on the build of GTA:SA Mobile Mod Force I Version, in which there are various modifications, one of which is an AutoSave game. My save game stopped working after I started the race Little Loop. And once took second place, immediately loaded the save game to beat gon in the first place, but the game just flew. After rejoining the game, the save game does not run, just beating the game. As I understand it, the game made an AutoSave, at a time when the race was over, CJ was awarded second place, and the mission is not yet over. I consider such solutions as:
1. Fix the saves. change settings from the last save point, or its offset.
2. Rollback the current saves on working a checkpoint save.
3. A complete copy of the contents of my save game to another, manually specifying the location of the last save and back to data races.

The options that I consider:
- The passing game from scratch.
- Download any working saves from the Internet.
Just want to add that I wanted to roll back Windows, but the last checkpoint was made too long ago.
If there are people who can help at the level of knowledge of the various aspects of the device saves the game or those who know how to roll back a specific file on a PC, for example in the condition as it was a specific number I will be very glad to have your help. Possible symbolic payment of your work.
And here is the save game: https://yadi.sk/d/OWdw6ZvNBvNjvA
