foobar2000 won't play certain .minigsfs

[TeridaxXD001]

I ripped some sounds from the e-Reader GBA ROM using saptapper. When I tried using foobar2000, they gave me an "invalid GSF" error. I've ripped the same sounds from the same ROM using the same program before on a different computer and they worked. Some GSFs work, like the music GSF release for FireRed/LeafGreen. However, the music GSF release for the e-Reader is suddenly incompatible, too. My own rips are all incompatible, though, regardless of game.

What's going on? Why is it different than before? I have the GSF Decoder plugin, along with some other video game format plugins. (By the way, I Googled "invalid GSF" and there are only two references on the entire Internet to the problem)

Here is a sample of what I ripped:
