Why isnt my user interface on my account not working?

I have purchased premium account access and my user interface is not working; i can not get into my individual forms to check the submissions or edit the form and none of the other links or buttons are working on the site. This is very frustrating.

I see that you are experiencing some issues in accessing the forms after logging into your account. It seems the issue is with browser cache. I request you to clear the browser cache by following the steps provided in http://www.wikihow.com/Clear-Your-Browser's-Cache 

Also, you may also try using a different browser. This should resolve the issue. Please get back to us if the issue still persists. We are happy to assist you further.
