I found a solution!
*Install the file contained in Hyundai 2015-10 Starter7x by DeMoN.zip. Execute the .exe
*Go to "C:\MCHYW\" (or the route of your installation) and edit the file "mchyw.cmd" in the line 6 with the date of your version. In my case I downloaded the version 12-2015. Example: date 1-12-2015. Save!
*Go to "C:\MCHYW\DeMoN\" (or the route of your installation) and edit the file "mchyw.reg" with the date of your version. In my case I downloaded the version 12-2015. Example: "TOP"="1-12-2015-0-0-8". Save!
*Now got to the desk and run the shortcut "Hyundai 2015-10 by DeMoN"
*If still not working change the system date to "October 1 2015"
I hope work for you
