I have a acer n50 premium pda I have when I try and active the blue tooth all I keep getting is a message that reads

BTTrayCE

Sorry! Bluetooth can no longer be used because the licence has expired

BDA:00:00:00:00:00:00
KEY:E3E53E19B3E8214426B4CO84522A7A737CC63DDO944134B

The above message is displayed in a white box with a red cross at the side. The Bluetooth device and not be found by others and it can not pair with anything either.

I try soft and hard resetting and this makes no difference PLEASE HELP !!!!!
