I really whant to play the wonders of IC2 with my korean friends please help ㅠㅠ

PS:I think the problem is because when i draged files from forge or mod loader 'when the computer said:this name with file already exists cover the file with the draged file?"
I clicked no because if I cover it with the modloader files an error acures in the server:
