Unable to connect to Git Hub

I am having issue with Step 6 on “Setup with Git and GitHub” here. I don’t know if it is related to the extra characters that are appended to the copy and paste (see screenshot) function or something else I may have messed up on.

Also, in the screenshot you will see the warning regarding the UI Helper. When I refresh the git hub page, as directed by the instructions, the repository does not connect as expected but the available command line options remain.

I am in a Windows 10 environment, 64-bit if that helps at all. Thank you so much for any insight!
