Short answer: No.
Long answer: Keep in mind that your question is not just for you. It's for anyone that will come after you and will have the same problem, for those who wander there randomly and for those that directly come to your question after a Google search.
What would happen if they came to your question and they took the accepted answer as the right one while it's actually a wrong one? No need to answer this... :)
You're here to get correct answers (other than good ones). You are responsible towards future visitors on what answers you accept. It's your question, but it's also not just your question, if you get what I mean.
Don't worry about your accept rate: I also have a low one on one of my sites. A low one doesn't always mean you're a bad user. It also means you simply haven't received a good answer yet. In that case, first try to improve your question, then notify under each answer for users to edit their answers. If that doesn't work, place a bounty if you have enough reputation.
