原因：第三方修改了ape文件的文件名，擅自加入了@圣城家園@空の軌跡，而播放器是根據(jù)cue里面制定的路徑來尋找文件的，所以找不到。
解決辦法：打開cue文件，查看內(nèi)容，找到FILE：

修改ape文件名為對應(yīng)的文件名即可，保證cue和ape在一個路徑下面，即可在foobar中打開。

p.s：如果開始foobar無法打開ape，那么是沒有安裝monkey解碼器，在官網(wǎng)上（http://www.foobar2000.org/components/view/foo_input_monkey）下載即可，放在foobar安裝目錄下面的compenent文件夾下面，注意此時要重啟foobar，才能保證新的組件可用。

總結(jié)：1. 解碼器一定要安裝。
           2. 根據(jù)錯誤信息找到路徑的問題，修改即可。
