So I go to the screen with the chart showing the differences between Basic and PRO. I select the "Basic" button, and it takes me to the screen with the download links for Windows, Mac, etc. But when I select the Windows download link, all it does is open a new window, which is the screen with the chart that I mentioned before. It will keep doing this over and over if I keep trying again. I really want to update to 4.6.0. Help?
