Audio not synced?

I've had a score up for a couple months now and decided to change a couple things. I changed what I needed to and updated it with the updated file but the audio is still the original. The score it shows on the website is the updated version, but the audio is still the old version. How would I fix this?
p.s. thanks in advance :)
