FmodDesigner won't build .fsb file from .fdb project file I was given

Hello, I have been given the original project .fdp file for fmod designer. I mad a few edits and when I try to build the project I get errors about missing audio files. I proceed and when it builds, It says “build complete with errors/warnings in 0:00 seconds” In the project workspace, theres an .fev file not an .fsb. I’m really confused.

You need the wav files. FDP is just metadata
