Well perhaps you should have read up a bit more before dumping in all that sulphite. Now you can either throw in the towel, and throw away a lot of money, or you could try and salvage your must and turn it into something drinkable. Many good suggestions were given in the other thread, I humbly suggest you follow them and make yourself a wine. A yeast starter isn't that hard to do so I can honestly see no reason to get upset about having to make one.
If all of this sounds like too much work, no one is twisting your arm to make wine, and I'm sure you can buy pre-made wine wherever it is you live.
