Experience with the Office 365 service upgrade

Hi,
I have Office 365 installed in my computer and I wanted to upgrade it so as to get the new functionalities that come with a service upgrade. But during the upgrade process I get an error message as shown below. Any help will be appreciated.

Error – Sorry, we couldn’t connect to the service right now.
Please try again later.
If the problem doesn’t go away, submit a service request.
