Need help with changing a feedback rating!

Hello.  I left negative feedback for HakurenKyo06 yesterday.  Today, the problem was hashed out and now I'd like to change the feedback to a positive rating.  I looked for ways to do it on my own, but no dice.  Can a mod help me out with this please?

I can confirm we worked things out and are seeking to change the feedback.

I deleted the negative.  You can leave another feedback.
