Hey! I had accepted this 3 or 3.5 hours ago. Thanks for posting, as I didn't know your displayed user name was the same as your github account's name, but now do so I could check into that for you.
That still may've been it, so logout from github and CS, clear your cache and cookies, restart your browser, then give it another try.
If that doesn't work, please let us know in more detail what the issue is, and also check out the posts above including the guide linked to from the top, as you may be able to figure out what went wrong from that. Thanks!
