Hi, as I have understood the demo for Deluxe edition should be out this Monday 5.11.2018 but I did not received any invitation, can someone confirm that?
Yes, the keys were sent out on Monday.
Did you get a confirmation from xsolla when you purchased?
If so, please contact Xsolla about your purchase at https://help.xsolla.com/
Thank you, contacting Xsolla support helped.
Glad to hear! 
I can confirm that!
