If none of those things help, please come back to this post and reply with all the information requested in that article above, especially:
1) Which browser and version are you using (eg., Firefox 3.5.9, Internet Explorer 7, etc.)
2) Have you deleted your internet cache / browser history of files and tried again?
3) Have you tried a different browser? This allows you to test if it is a browser specific problem vs. a computer / network problem. We suggest Google Chrome or Firefox.
4) What is the specific error message you received?
