After many problems with drivers and drives I successfully installed Vista yesterday and just love it...

But...in the attempts to install it which failed I inadvertently left the default "authenticate online" box ticked. Now that I have a successful installation it won't accept the Product Key, giving me an Error Code: 0X80072EFD. Presumably I have used up the number of attempts I am allowed.

I tried downloading it again using different email details but the server is too smart for that and will only let me order the CD, which is no good if I still can't authenticate it (I assume it will still have the same Product Key...)

Only have twelve days left now...can anyone help, please!
