Recently I wrote an answer here. Initially it was incorrect, but now I feel that I have corrected it to the best of my knowledge. There is no other answer on the question either. Another answer was downvoted similarly, although it was correct in the first place, as even the original poster has acknowledged my answer to be legit, although he hasn't upvoted it. I wouldn't bother so much about it, but now I am unable to post an answer to other questions (answer ban has been imposed on my account).
What am I supposed to do in this deadlock? Should I request the original poster to upvote my answer (I consider it impolite)? Or does it need moderator attention? Or should I delete both answers, so that I can start anew? (I have contributed only two answers so far and am willing to contribute more...)
