Oh, I see. :0 Perhaps it's a matter of turning on preferences for adult content on your Steam account itself, then? Because when I'm logged into the NBS account, I also get the message that "1 item has been excluded based on your preferences", while I can see the patch just fine on my personal account.
Here's the link to the patch itself, if you'd like to check out if it opens up for you at all.

Hi, thanks again for your reply!! And now we have proof: when I click on your direct link, Steam tells me I can't access the page in Germany. (My preferences are always including any adult content.) So it's indeed blocked for German Steam users, which infuriates me ever since they changed it to that a few years ago, as it isn't even necessary by German law, they would just need to implement an age verification. >:( It's really ridiculous, when not even porn sites are blocked over here. Well, rant aside... do you have any idea how I could still get the file?
