The problem is - as you noted - always in the cue file. I did't try to look into those files just because it sounded strange to me that the problem could be there. But so it is.
The FILE command is the
only link between the cuesheet and the file that contains all the data.

If you are editing your cuesheets bear in mind that most (generally talking WAVE or lossless files here) will take the format:
CODE
FILE "filename.xxx" WAVE
... but you may also use:
CODE
FILE "filename.mp3" MP3
... or
possibly:
CODE
FILE "filename.aiff" AIFF
The easiest way to ensure that the filename is correct is just copy it from Explorer into the cuseheet. You needn't have the cuesheet and file in the same directory (you can provide an absolute or relative reference to the file), but it is a lot easier to do so - and just reference the filename as all examples thus far.
Edit: also, bear in mind that foobar 0.9
currently still
has issues with cuesheets using MP3 or AIFF as the FILE type. Stick with 0.8.3 for now.
