Playing Shift 2 Unleashed Audio Problems

I tried to open Shift 2 Unleashed’s loadingmusic.fev and music.fev, using FMOD Event Player v4.36.04 but it gives me a “FMOD Error (25) : Unsupported file or audio format”, although I didn’t alter their original .FSBs, also, what does FMOD Error 25 means?

We no longer provide support for that version. Try reaching out to the Shift 2 Unleashed community for help.
