Thanks for the comments everyone.
Meanwhile there are updates available for this campaign. I also put together a PDF installation guide which should provide better info for installing, updating and playing this campaign.
As it seems that gamefront introduced a rather absurd blocking policy for many countries a while ago, I will host my files mostly on sendspace for the time being.
Mod files incl. updates are available here:
Sendspace:
Main Mod
v0.8 GME files:

Update
v1.0 Scenario files:
http://www.sendspace.com/file/ria9uz (ca. 250 kb)
v1.0 GME files:
http://www.sendspace.com/file/03nspf (ca. 11 MB)
In short, people who have the first release version only need to apply both updates. For a completely new installation install all three files. Please consult the PDF guide below for instructions how to install or update...
