Yeah that's weird, I'm trying my own now and it's failing, even though I've downloaded it before. Maybe wait it out? Or if someone has the update package stored locally maybe post it up?
You definitely start with the letter E in your VIN though; mine does too. Fun fact: That letter tells you which plant assembled your car. I believe E is Regensburg.
EDIT: Now entering the VIN just causes the blue circle to keep spinning; maybe their site is being hammered, or perhaps they're in the process of posting a new version of the update.
