Hi Marschen, 
 Is it only the consumer page HID reports that cannot be sent, or does this apply to all data?
If it applies to everything:
have you tried connection the ble_app_hids_mouse example to the Master Emulator?
Unless you have a Bluetooth sniffer at hand, that is the easiest way to see if the data is actually being sent from the nRF51822 to the Central side. 
 A number of things can cause this situation, determining if the data is actually sent will help narrow down the possibilities. For example, if the bonding keys or system attributes aren't properly stored to flash (see ble_bondmngr SDK component) they will be lost when nRF51822 is powered down. If they are lost, Win8 will connect, but the link cannot be encrypted and data is not sent.
