1. Turn on Hidden Files + Folders (Google if you dont know how)

2. Go to:

Win Vista/7 - C:\ProgramData\Test Drive Unlimited

XP/NT - C:\Documents and Settings\All Users\Application Data\Test Drive Unlimited

3. Delete CDKey.txt (and addon.txt if it exists).

4. Launch the game - it should prompt you for your new legit Authentication Key.

 

If that doesn't work, you may need to uninstall the game, remove the above files, and any registry keys for TDU1.

I tried these steps but it's still not working. I tried to install TDU on clear notebook and same error....HEELP :_((

Did you have an illegal copy before you bought the game?

oooh Yes I have... so what next? :(

Did you buy the game or get an illegal copy?

Do you have the mega car pack installed? Did you buy that? Did you activate it using the megapack key and not the normal game key?

I buy original game... i dont have mega car pack installed only patch 1.66a.

i have got same problem but i can't solve it :( i have installed patch 1.66a and turned off my Firewall but it says Invalid authentication key please help
