EWS Problem

[Cosmin 27]

Hello guys! Maybe someone can help me,i tried to make a new key with ak 90+ and was not possible,i put back the EWS but the car it's not starting anymore,i talked with one guy and he told me the EWS it's corrupted. I installed back the BIN file that i saved before tring to make key but the car still not starting. I tried to put BMW scanner and i got error "hardware not ready". Anyone have any ideea how i can start the car?
This guy just had the ideea to send him the DDE+EWS and he have a BIN file from another E53 with EWS 4.3 and he can read my DDE ISN NUMBER and edit that bin file from another car with my car ISN VIN KM etc. and write on my EWS,will this work?
