So u don't understand, don't u?
There only exist 2 keys of this game (US&EU)
The error we get doesn't really mean that our key is wrong, it just means that the disc we use is no original. I tried this with Tracmania Sunrise which is protected by SF too. But there error is a lil different but it causes the same. It tells me that SF wasn't able to identify the entered disc as the original and that I should proof if it is the original disc.
This just what SF of SCCT is trying 2 tell us. The key is correct!
So try whatever u want but u won't have any success.
Physically unplugging doesn't work too
