you need to download everything again since all of them got updated to match the new contents.
the game+DLC1+DLC2.
1-cut the DLC1 data file into the main game file and overwright when asked.
2-DLC2, it comes in 2 files.
the first file comes as an exe file format, make sure both files are in one location,
after that double click on the exe file and say yest, it'll extract both files and merge them into 1 folder,
if done correctly, the DLC2 file size should be 3GB. cut the DLC2 data file into the main game folder.
if you did it right you'll get both DLCs simpol at the main lower start menu.
