ESU has update the LokProgramer software:
The new firmware 5.5.141 for LokSound 5 decoders will support a new brand of flash memory IC that will be used in the production of LokSound 5 decoders. This additional IC has to be used because of availability problems of the original flash IC brand Outlook and functions of these decoders is unchanged, but they need the new verion 5.1.6 to be used. We highly recommend to update your LokProgrammer software.
