File format is not suspect, any file - like a powerpoint presentation - would be played, likely only resulting in noise or glitchy sounds, but not a crash. If the samplerate 'd be off, it would still play but transposed. If it'd be a 32 bit raw file, it'd sound distorted and at half speed. Play a .wav file, and you will get a click resulting from the file header played back.
1.0.8 is improved in reporting file access errors, and also added support for long filenames. 1.0.6 is limited to 8 character filenames with a 3 character extension.
