When I try to build my master bank in FMOD, Unity says that Master.string.bank is not a valid bank. I am using Unity 645f1 and Fmod 2.03.07

Hi,

Thank you for sharing the information and version number.

This error is often caused by a version mismatch between FMOD Studio and the Unity FMOD integration. Could you please check the version of your FMOD Unity plugin? You can find this information by navigating to **FMOD \> About Integration** in the Unity menu.
