If you're using IE (MS Internet Explorer) can I respectfully suggest that you download and install Firefox? It's a much better browser and will enable you to log in.
If you're using already using Firefox, there is a good utility in options to allow you just to delete your cookies. If this doesn't work then you may be able to log in using IE.
