I am having trouble authorizing flickr from LR4 on a MacBook. I was going through the process but had trouble remembering my flickr password and so shut down the browser. Since then when I click on Authorize I simply get a 'not authorized' msg with no pop-up browser. I checked my flickr account and there is no sign of a LR account linked to it there. I have tried disabling the plug in and enabling it again hoping that would set it right. I am hoping there is an easy solution for a problem caused by me!
