Cannot login or connect to Microsoft account

Since installing the new version to go with my Band 2, I cannot login or connect to my Microsoft account.
(my MS account works perfectly well when connecting to other MS services).

I was very happy to get the new Band 2, it is a shame that the Mac sync software from Microsoft is at expected level of quality.
Hopefully Microsoft will get this fixed soon.
