A "checksum" is a calculated value that is used to detect errors introduced during data transmission or storage. This message is returned when a routine attempts to read a model file and the checksum of that file differs from the expected value. This is an indication that the model file is corrupt.
User response
If you believe that the model file might be corrupt, regenerate the file and repeat the operation that caused this message to be returned. If you are certain that the model file is not corrupt, you can disable checksum checking by editing the file and setting checksum=*.
