Please check your PC's date and time as sometimes this can be the problem.
For the last 3 days I have been ahead of my auto downloader in downloading updates. Which I often do when more than 1 update show per day.
Each and every one corresponds to the version and date given by c/net.
After updating the "internal data base" shows that the date has an error. The month of June is highlighted.
All dates correspond to the current month,date year.
Tomorrow morning the grey icon will clear and the dates will be current.
