What e-mail account are you using between the two? If it is a Microsoft Account (live/Hotmail/outlook) then you may have multiple calendars and contact lists. You need to make sure you are adding calendar events or contacts onto the Microsoft Account's calendar or list.
If you go to calendar and see your events: look on the bottom-left and see if the calendar you are viewing says "this computer only" on it. If it does then that will explain why nothing is synchronizing between devices.
