Hello again,
Something else that comes to my mind.
Once you complete the steps above, please download and run this tool again:

Once you are ready, please restart your computer. Use the *restart* option, not shut down and start again - restart :)
Check if this resolved the problem.
If not, check your computer's date and time.
Check your timezone and regional settings in Control Panel -> Region
Once you are ready, please restart your computer again
Looking forward to your update - please let me know how it goes.
