Cheaterflums

hey guys, I am new here, so here is my problem: I wanted to update my f940bt (radio update). I did it step by step like on http://www.pioneer.eu/files/support/AVI_Tuner_Update/Update%20procedure%20AVICFx40BT.pdf As far as good, but then the update failed, the device started up again and now it only shows "There is no appicable program" So what can i do? Thank you guys and sorry for my bad english.
