OK.
The sediment could have come as a result of bottling so soon. Most of us have never figured out why these kit manufacturers are in such a hurry to bottle unless they are afraid the wine may oxidize. The wine needs 2 to 6 months bulk aging before it will stop dropping sediment.
The other reason for sediment might be if the wine started fermenting again in the bottle. If that happened, you would have gotten a huge pop when you opened a bottle, like with champagne, like a blow-the-cork-off pop.
You might try decanting for an hour before drinking; that might help. You are going to have to weigh the idea of drinking a wine that smells so bad, compared to just dumping it and starting a new kit. Problem is, unless you know what the problem really is and what caused it, you may end up with a similar problem the next time.
Wish I could help you more.
