Did the buzzing occur after you completely loosened the string and then re-tuned it?
If yes,then tighten the string to any realtive tuning and then after say every 15 mins. try to bring it closer to the std. tuning.If the buzzing exists try tuning it a bit higher than the std. tuning and then bring it back..works.
However,if the buzzing occured before completely loosening the string,you'll have to increase the height of the bridge..
