Unfortunately I can't remember when I purchased it... I have a feeling it might have been 2012. There is a white sticker at the back of the HD that came with. It has some capital letters and a 3 digit number but no serial number.

Since then I have purchased additional standard versions, pro versions and a megapak too. So maybe whenever I was upgrading versions accross the different computers, I managed to somehow cockup the file system? I don't know.
