I did it with Notepad ++.
Theres a function to replace all the russian names to a name of your choice.
1. check all "missing" objects with maptools
2. head to sceneryobjects and find the folders with russian names
3. open notepad ++ and press ctrl + shift + f
4. paste the russian name in the 1. field
5. rename the russian folder with an other name
6. paste your name in the 2. field
7. in the 3. field write *.map
6. in the 4. field head to the map folder
7. change settings to the settings i showed in the picture
8. press the 2. button on the right and click ok
9. Done!
Check map tools again and do this with every folder that has russian names.
Took me 15 minutes.
