I also newly installed CCGV and my problem is I cannot find Voucher/Coupon show under admin control panel so I could not create any coupon. I found those tables in my database but not showing on the admin control panel. It shows under admin/configuration/My Store/to enable it and in admin under order total to set amount but that's it.
Since I think you have better knowledge on this then I do, I try to ask you, sorry I am not replying you issue. But I have posted my problem but nobody reply me too, can you help me with this. Thanks! :)
