Hey people,

I unfortunately upgraded my FMOD project from 2.01.11 to 2.02.03 and now Unity doesn’t want to load Events and Banks.

The error message is : FMOD Studio: Encounterd Error: ERR\_VERSION The version number of this file format is not supported.

Someone has any idea?

Thank you!  
Max

You need to ensure the version of FMOD Studio and the version of FMOD Unity match. In Unity click on FMOD \> About Integration and make sure this is the same as the FMOD Studio application you are building banks with.
