1. Cool to have an altenative download location! Thanks EStar!
2. I did some testing and it seems NOT to be an issue with the NWN-vault, but more an issue with a browser and the fileformat .7z AND .rar:
I am curently using Firefox and yes, if I Left-click the dlcr_xyz.7z-flile, Firefox opens another window with lots of cryptic things showing (probybly tries to display the archive as a webpage).
BUT, if I RIGHT-click it and choose "save file" (or something liek this: I have it in german here and the function differs from browser to browser, but there is a choice to download/save it), the download-window opens. I successfully saved it and checked the content - it was ok!
I did not have this issue with .zip-files (eg. our creature-haks). I could LEFT-click them in Firefox and download them. And I also tested it with a (old) version of the IExplorer (which I don't use, so it's not updated) and here, the download also worked for .7z-files (left-click). So I guess, it's a browser-issue.
I will do some more tests and if it works via right-click, I'll (additionally) repost the vault links.
