Event Player Access / Older Versions?

Hello, I have a bunch of .fev and .fsb files from a game that came out in 2015 and I want to play and extract the individual sounds within. I found FMOD Event Player v4.44.63 on Internet Archive and launched it. When I load files corresponding to entities (for example, “sprj_c5280.fev”), it seems to work without a hitch but when I load ANY OTHER .fev file in the “sound” folder, it shows all the sounds like normal but when I try to play one it gives me “FMOD Error (25) : Unsupported file or audio format.” Does the newest version have better luck with this kind of thing? If not, can I have access to some older versions?
