Helium Scraper

Hi, I'm trying to use Windows Task Scheduler to automate HS as per the instructions - http://www.heliumscraper.com/en/Help/commandline.html, but I keep getting this pop-up message that stops Task Scheduler from running; “The project you are opening seems to come from an external source...”
I've tried putting the project file in the same location(Users-user name-AppData-Roaming-Microsoft-Windows-Start Menu-Programs-Helium) as the .exe file, but it still won't work. I'm using Windows 8.1.

Anybody else have experience with automating H.S?

Thanks in advance.

open the helium file on the computer that is running it. you will more than likely get the same error. just click 'file' and 'save' without making any changes, and the issue should go away.
