It works mates.
1. Stick the updater in an empty folder
2. Open the updater ,wait a second then the updater will
give u three options
3. Hit the number (1) up which means (install game)
and wait for it to download
Thats all tho and if u wanted to pause the downloading up to rest your pc or to do anythin (exit the updater ,do ur stuff, then when u want to resume it just open the updater again but use the command (3) that repairs your game and download the missing files.
