This is usually caused by a formatting error within the file's internal chunking structure. Older versions of JRiver had a bug that caused files to be created with an incorrect chunking structure.

You can fix this by doing a file conversion using a converter program such as dBpoweramp. The output type for the conversion should be the same as the input type, such as FLAC to FLAC or AIFF to AIFF. The conversion won't change the file's tags or audio data but will fix the formatting error.
