Sorry about that.
Possibilities:
1. Trapped by your ISP as SPAM
2. Trapped by your e-mail client as SPAM
3. Put it to an incorrect folder by your e-mail client
4. You unsubscribed from our list
5. You changed your e-mail address
6. Something broken on our end
Thanks, possibilities 1, 2, 3 are not applicable due to the way my emails are managed
.
4, I've not unsubscribed
5, My email address is way too cool, like me.

6, I can't confirm that I am still on your mailing list or that anything has been sent to me since 27th May 2016. I have however received Temporary Install Keys (for 21/22) on the 10th of July 2016 and 24th of July 2017.
