I've tested the token retrieval under IE 11, Firefox 30, and Chrome 37. What browser and OS are you using? If using NoScript, make sure to allow the page instead of clicking the link it provides.
If the url of the page contains an #access_token=xxxxxx string, you can manually copy this token into twitch.ini under your channel's section as token=xxxxxx. If the url does not contain that string, please respond with what it does contain. Requesting multiple tokens should not be a problem.
