Sp2 and bluetooth does not work

Since i recovered my computer to windows XP Sp2 my bluetooth connection
with my cellular phone does not work annymore.
It seems like it will work but at the moment de actual transfer of the file
must start the program
gets stuck.
The phone and PC handshake an every thing seems fine but when it comes to
transfering the file,
the pc gets stuck and the only thing to do is "ctl- alt- del" and end the
program.

Before i did the recovery it worked good!!!!.

Everything already tryed but like a new window installation. but no result.

Does someone have a clue?
