Name for Creator X is one byte too long; MakerBot Desktop throws an error when it reads the 16byte string from EEPROM and doesn't see a NUL terminator.  Change in behavior from earlier MakerWare.  But at least Desktop sees the error rather than corrupting its memory.  Anyhow shorten the name.  Thanks due to 'Fogl' for diagnosing this.  https://groups.google.com/d/msg/flashforge/sAWE00zTowA/bUqbclr_3ScJ
