My experience was a breeze too - also the activation
I was on the european server and the speed for Secrets of Atlantis was around 460kB/sec.
Right now I'm downloading the english version of Jack Keane from Gamersgate and my speed says 584kB/sec. - that's actually quite high for me
Out of curiosity what's the normal speed for your EU servers, and where are they located?
Oh and since my question never got answered, why is it, that the EU server has Barrow Hill and Keepsake and not Undercover: Operation wintersun?
