This usually indicates that the memory in the unit has been corrupted (usually due to a failing internal backup battery). You probably need to have the internal backup battery replaced. This requires complete disassembly and soldering and is a job best left to a professional. In the US, Patchman Music can do this for you. After the battery has been replaced, you will need to initialize then reload your sounds (see next section).
