There has been a sporadic problem with some LPC2xxx devices where the device failed to transmit line feeds. Unfortunately both NXP and ourselves never had a device in front of us that failed in this way.
Version 4.10 of Flash Magic is now available that works around this problem, so if we previously diagnosed your problem as the missing LF issue, please give it a try. If you run into problems post a message so we can take a look.
