Google's Chrome uses, as many other browsers nowadays, an in-built security option.
Maybe this helps: Go to Settings -> scroll down until you read Additional settings at the end, click on it -> in the next chapter Privacy and security disable Safe browsing -> delete browser cache and cookies, log into CH and try again.
I know this is a couple of months old but I'm experiencing the same problem. The way you described how to get to settings doesn't work on google chrome unless I'm supposed to do that somewhere else. It gives me this message at the bottom.
I realize this thread was dismissed, but it looks like the latest chrome update is blocking all downloads from CH. Just an FYI, because I'm sure this will be an issue you'll see more of as the update is pushed out.
You can disable the Chrome security settings, i have no issues here with chrome.
