Can't install GSC Extreme DVD

Good morning from Germany,

I received my ordered DVD with GSC Extreme 2 days ago. Yesterday I tried to install the game but it came to this error:
[You must be registered and logged in to see this link.]

My OS is Windows 7 64 bit... any ideas ?

with the dvd you got a key too?

[You must be registered and logged in to see this link.] download the game there, install it and use the dvd key

Yes, this way I also tried it but the key which came with the DVD doesn't work. Provided key inside the box is printed on a sheet of paper and has this form:
XXXXX-XXXXX-XXXXX.

I bought the game at [You must be registered and logged in to see this link.]

Now I complained there. So I can't participate in the test run today.

checked if theres another installer exe? and you can try to copy all files from the cd to your hdd and start the setup.exe from there

tried to tun it as administrator?


btw this is an older version of the game too

wip, currently copying all files to hdd...

I also bought the DVD version but registrated through Steam.
I had the same CD-key form.
