Help with ROM update

[kamma]

hi, i'd like to update ROM in my wizard, but i get this error message : "ERROR [294] : INVALID VENDER ID".
i try to upgrade to ROM : "RUU_Wizard_225111_22511102_022511_CWS_WWE_Ship.exe"
and now i have this ROM : "MrClean_RUU_WIZARD_224a_AKU23_WWE" on my wizard.

any suggestion ?

thx
