Mixdown/Export Plays Back at Higher Speed

Hi, I updated to 9.02 and tried to mix down a short bit of audio for a client. The mix came out at a higher key; the track had acoustic guitar, piano and drums. They are playing back a whole step to a minor third above. Has anyone seen this issue?

Wrong sample rate for the mix?

This was actually a Windows issue – mismatch on audio sample rate and bit depth. Fixed now.
