@Mike_Speller - I split your post into its own topic so people are more likely to see the issue and respond.
Have you tried temporarily disabling any firewalls and anti-virus software to ensure that nothing is blocking access?
I am just replying to let you know that I have Windows 10 and it is working (albeit with many improvements needed…) but I am not getting the error that you are. Mainly replying to make sure you know it does work in Windows 10, in case that was part of your original query. Sorry I am unable to help much beyond that for this particular error.
