Hi Todd,

I am having same problem. I tried to upgrade to 3511, followed the steps with the USB pen drive and all went fine.

After reboot I get "BOOT ERROR" on the screen and thats it... I remembered I once had a similar problem and fixed it by reupgrading the DOM, but if boot again from the pen drive and try that with 3511 as soon as I hit on "Use Product Key from existing version" I get this:

Error encountered! Code: 1229
Please contact support.

Should I try to rewrite the old version (3278) to the dom with the CD?
