10% coupon to register virtuemart

hello,
I created a coupon for 10% of virtuemart registration expiring 30 days.
My problem is that the coupon is not generated and cleinte not receive emails with discount coupons.
Please help me

Looking at the images you sent me, I see that in AwoCoupon Email, you have test mode set to yes. This is the same having the plugin unpublished. Set test mode back to 'no' and it should work again.

fully ask your pardon, I had not noticed my mistake.
Thanks for your help!
