Yes he is I'm using just now NOS Doesn't work for me too.
Does your game version match the trainer version? Are there any special instructions that need to be followed? Are you running Aurora as admin? Not doing that can cause issues for a lot of trainers. Did you extract Aurora as opposed to just running it? Have you reinstalled/verified the game files? Have you restarted you computer before trying the trainer again? Have you set the anti-virus exclusions for Aurora?
To answer your last question no I don't have an antivirus software and Windows 10 (however, I do have it on Windows 8). Yes, the trainer version does match the game version as for running Aurora as an admin I haven't done that yet but I'm going to try it as for the rest of the stuff I don't think it's necessary for me to do that.
