I want to play R6 Rs on the net but each time they tell me that the server have a higher version than mine. I have token the 2.05 french version patch and when I installed it a message appeard: old file not found, however a file of the same name was found. No update done since file contents do not match. RS has been successfully updated to version 2.05.
but when I tried to connect to an internet game, the same message from the server appeard. I tried to install urban operation, same thing, WHAT'S WRONG!!!
I'm so discourage of it, thanks for help!
