We are working on an issue which is preventing some users from accessing our control panel from specific browsers on specific operating systems. Primarily we have seen this issue with Chrome on Windows 7. This issue is due to a critical Microsoft security patch we applied on Tuesday November 11th. Microsoft is aware of the issue and we are working with them on a workaround to the problem which we hope to have in place on or before Monday November 17th. Until then, if you are experiencing problems accessing our Control Panel, please try a different browser. We apologize for any inconvenience this is causing. Thank you for your patience.
Update 2014-11-16 9:28 AM EST, we have deployed a workaround provided by Microsoft which appears to have rectified this issue. If you experience issues accessing the Control Panel, please let us know.
