Pam, I've posted a fix for this today. This is generally a cookie cache issue. Try this depending on the browser you are using:
For Google chrome, you go to history>Clear browsing data>Obliterate the following items from: The beginning of time(everything for Firefox)> and the 1st, 2nd, 3rd, 4th, and 6th options should be checked off(1st, 2nd, 3rd, and 4th for Firefox). (you do not need to delete saved passwords)
For internet explorer (or Firefox)follow these steps: Hit Ctrl+Shift+Delete and the following options should have a check mark on them: Temporary internet files and website files, Cookies and website data, History, Download history, and form data.
If this doesn't work, try rebooting your PC. Please give CS a call if you continue to have trouble. 847-944-8200. CS will gladly honor the promotion if you missed the window. Take care! =)
