K1dd0: yeah, thanks for the attention.
Guess I just gotta wait till next week.. sadly.
Okay, i wasnt gonna post this since editing the registry isnt something to reccomend to everyone since it can really mess up your pc if you screw up.
Sooo....
TRY THIS AT YOUR OWN RISK!
And be careful!!!!
First close the Witcher launcher if its open.
Then....
Start / run and type regedit and hit enter.
In the registry go to
HKEY_CURRENT_USER \ Software \ CD Projekt RED \ The Witcher 2 \ Downloads
You'll see a RED entry labeled as (Default) in the right pane, DO NOT TOUCH this one.
Delete all the BLUE ones with numbers under the RED (Default) one.
Now try the DLC again.
Doesnt work for 100% of people but it has been reported and confirmed to work for some.
