I have just downloaded MPLAB 3.21 and installed it all, but when I come to downloading the new firmware for promate from MPLAB it starts gets someway through then stops throwing up a message to check serial and power leads. Does it work or is it my system ? Paul Waterfield Exhibit designer Techniquest Stuart Street Cardiff CF1 6BW UK T +44 (0) 1222 475 475 F +44 (0) 1222 482 517
