I was trying to upgrade my 2001 E39 530i car purchased today and the upgrade appeared to go flawlessly but when it reboots it comes up with a text message:

"Please insert key CD or version 17."

Please help !
thanks,
Seedar

PS: I have since tried upgrading/downgrading to versions 24,25,26 and each one reports "Already Updated" but then doesnt start and again reports:

"Please insert key CD or version 17."
