I have tried using anytime upgrade to upgrade my netbook from starter to home premium / ultimate / pro but every upgrade i try fails during the percentage screen. the system reboots in the 30%s and continues the upgrade all the way up to 100% then a message appears saying that the upgrade has failed and system is being reverted back. What am I doing wrong? I have tried many keys and dont seem to be getting anywhere. When i upgrade my laptop it took literally 15 minutes and was simple first time. I havent installed SP1 on the netbook but have performed all updates apart from this. Any ideas? is it maybe that the keys on youtube etc have been blacklisted?
