Had trial version of home office, now purchased the year version but having trouble logging in

I had free trial version of office 365 home professional and then I purchased the yearly subscription.  Now when I log in it says I have pending changes.  When I click on the button to log in, it states servers are busy and try again.  If I exit the application I can log in from microsoft main page.  This happens on the 2 computers I use with 365.  When I go to my account it states in one part I have no office installed and then the next line it states I have 2 installed.
