I have been unable to log in for a few days now? I don't like deleting cookies as it means more hassle signing into forums etc
you should be able to view your cookies, and delete individual ones. not sure how to do it in internet explorer as i am on a mac at the moment. but in firefoc, click > tools > options, click > cookies tab, then view cookies and you can find the ones just related to adwords.
