It seems all download links for Nimble Kick 1.0.3 get blocked by chrome, because the webpage is declared as "hacked".
Also checked the file (Windows setup version) in virustotal:
The "This file is not usually downloaded" warning is common, and safe to ignore. The virustotal report is a false positive as well. The error you're seeing does not mean it's "hacked". It just means the file is new and Chrome just doesn't know it yet.
Just use the "Keep" button to get access to the file.
