Well it's so slow, I don't know what this can be.

You may want to post in the technical support area so they notice it more qiuckly. As Annatar mentioned, downloads from Impulse are usually MUCH faster then this (I get over 400).

The ping is that high because I live in europe, but the dl speed is still stuck at 40kb/s ...

I downloaded "Left 4 Dead" on Steam some days ago and the speed was 1.5 - 1.6 mbit/s and I think Steam's servers are located in the US aswell.

Is there any other possibility to load the Installer via Rapidshare or sth like that?

You can try downloading an installer and archive files for the game by signing into Impulse Anywhere with your Stardock.net account.
