Hi Kevherb,
I understand you're getting frustrated about this demo problem...but well, just as you said, i think you're overlooking something very simple.
You said "have only been emailed an activation code for the miniMg and the license".
Then copy this activation code.
Open your eLicenser Control Center, click on the "enter activation code" green button.
Paste your code.
And that's it!
The eLicenser will download your 15-day trial license and then you can start using your MiniMg.
I really hope this is clear,
Best regards,
Denis
