Why can't I upload the 10 OS?

Hi all - This is driving me up the wall.
1) I receive the notification in the BB Link that an update is available.
2) I connect my BB Z30 to the PC.
3) The Link tells me to disconnect all BB devices.
4) I do.
5) The Link tells me that no device is connected and the update cannot run.

Catch 22 is alive and kicking. What can I do to finally download the upgrade?
Thank you!

Check on the phone instead. Settings->Software Update. I'm guessing it will say up to date, and you can ignore silly Link, which itself may need an update.
