Thank you for your post!
I'm sorry for any inconvenience. Here are a few potential solutions:
1. Clear your cache and cookies. Here is a list of guides for how to do so in different browsers, if needed: https://kb.wisc.edu/helpdesk/page.php?id=12384.
2. Try in private browsing mode. Instructions: How do I set my browser to Incognito or Private mode?
3. Test in a different browser, preferably Firefox. You can download Mozilla Firefox, if you don't already have it, here: http://goo.gl/7ICv2
Please let me know if your issue persists, or if you have any further questions. Have a great day!
