This error indicates that the internal memory in the MMS/Profiler instrument has been corrupted somehow. There are a few ways that this can happen, such as the battery going dead during a recording, or possibly an ESD spike transferred through the sensor cable to the instrument.
In some cases it IS possible to send the data to MAS, so you should definitely try this first.
Next, begin erasing the most recent recordings one-by-one until the memory error disappears. Turn the instrument Off then On after each deletion. Once the corrupted recording is gone, and the memory error cleared, the instrument will begin behaving as normal.
In some cases it is necessary to go to the Memory Management screen (or File menu) and use the "Erase all recordings" option.
To help prevent these errors in the future, make sure you are using the most recent version of firmware for the instrument.
