The correct way to handle this is to [open a bounty][1] on the question. Unfortunately, this is not an option for new users. You can either wait until you have enough reputation (75) to open a bounty or a higher rep user may be willing to open a bounty on the question for you to get an updated answer. You will need to include a link to the question for that to happen.
