DOWNGRADE GTA SAN ANDREAS v2.00 TO v1.00 
How many know the version 2.0 of gta san andreas does not allow the mod. 
Like you I had version 2.0 and now turned into 1.0. 
I advise you not to use the downgrade patch because it does not work. 
It is not enough to replace the gta_sa.exe 
But now we begin: 
1) replace the files script.img and main.scm with the original ones that are in the scripts of gta san andreas. 
The scripts folder is located in GTA San Andreas \ data \ scripts 
2) replace the file with the original gta_sa.exe 
You are done .... 
Recommendations: 
When you start the game the default language is American and you can also choose the Spanish but if for example I want the German language. Leave the game and go in the text. Rename the file american.gxt as american2.gxt and german.gxt as american.gxt and if you start the game you will see that the language is German. 
IF YOU HAVE PROBLEMS WITH THE SCRIPT CLEO WILL HAVE IN THE DOWNLOAD FOLDER gta_sa_compact.exe that should be in your gta san andreas. Remember that when you put the gta_sa_compact.exe you have to start if you want to play gta san andreas.
