Can not get new game to work properly. Any step by step protocol to use this feature?

It would be helpful to know, which game you are referring to.

What game and what feature? More information would be helpful.

I'll take a random guess and assume that you're talking about the New Game+ of Witcher 3?

Contact support and ask them for help.

- Go to the support tab in the menu
- Go to games support
- Search for your game
- Check if your issue is already mentioned
- If not, click on "I can't find solution for my problem" on the right
- Send the email to support and wait for an answer
- If they can't help you get it to work, you're entitled to a refund

Or, just ask on the subforum of the game.

If it is about NG+ in Witcher 3 do this:

jettstiles:

"[...]
- load a completed savegame
- save it again in a new slot
- quit to the main menu and load the game again (once loaded you should get a popup saying that NG+ is in the game or sth like that)
- Start a NG+ and select the savegame you just made
[...]"
