Required to buy a key after update?

So I’ve had a 1tb My Book for a while now and never really bother to update it.  I finally did it, and it’s asking me to upgrade to the WD Smartware Pro version, but I need to spend $30.00 to do so.  I updated it from inside my existing software and can’t see why it would need me to buy an activiation key when I already bought a WD drive.

If this update actually requires me to pay an addition $30 on top of what I already paid for the drive, you can bet this drive is going to end up right in the garbage.

Turns out my drive accidentally became unplugged and what I needed to pay for was dropbox storage.  I should have realised when the drive wasn’t showing in my computer.  My bad.
