Error when attempting to connect to the windows Live Calendar service

Hi,

I'm getting this error when using Windows Live Mail 2012:

"There was an error when attempting to connect to the Windows Live Calendar service. If the error persists, check to see if there's an upgrade of Windows Live Mail available or contact a service representative."

I've read many, many posts of people with the same problem but nothing that has been suggested has helped me.

My mail and contacts are updating fine.

I can access my calendar on the web service at www.calendar.live.com. I can also access it via my Windows phone. Any changes I make to either of these two calendars is instantly reflected in the other, but nothing shows up on my Live Mail on my computer (Windows 7 Home Premium, 64-bit).

I have tried uninstalling and reinstalling, as well as repairing Windows Live Essentials. I have checked I am online and signed into the correct account.

I have looked at the log of the Calendar in the Live Mail store folder and it is showing "ERROR: (wcsseadapter.cpp:264), failed with 0x80072EFF".

I'd appreciate any help, it's starting to drive me crazy!

Thanks.
