Those are fair points @Jaslan, see below:
Here is the text part of what I got:
Update to the latest version of Cubase LE for free
Are you using Cubase LE 4 or higher? That’s great, because we have good news for you: You are eligible for the free update to Cubase LE 10.5. Get started with Cubase LE 10.5 and check out all of the latest features and improvements.
All you have to do is enter the activation code from this email in your eLicenser Control Center, download Cubase LE 10.5 in the Steinberg Download Assistant and install it.
Download and install Steinberg Download Assistant
Run Steinberg Download Assistant, and choose Cubase LE from the list of products on the left-hand side.
NOTE: They also sent me a legitimate license key as well, not posted here for fairly obvious reasons
I did all of those things and everything has been fine until license activation. It could be that way back when I had LE on some long dead machine that I wiped and forgot about years ago.
