Some people, downloading the demo using Google Chrome, are getting a warning that the file is “not commonly downloaded and could be dangerous”. The file is actually fine, the warning is due to it being new and Google not having records of it. The error should stop as more people download it. Unfortunately, as the file is hosted on the Amazon Cloud rather than my own site, I can’t speed things up and force Google to index it, meaning I’ll just have to wait.
Again, I assure you that the file is fine, Google just hasn’t caught up with it yet.
