We have received quite a few emails/phone calls about our Calendar not opening for you. It seems to work for most people and we are trying to resolve the issue. However, if you are having trouble can you please email us at email@example.com and let us know if you are using a computer (which version) or apple and which browser you are using (Internet Explorer, Chrome, etc.). If you are using a smart phone, which type and do you have the latest updates.
Thank you so much for your help and understanding!
