Before you execute the firmware update program close all other progs and then execute and don't touch anything while it updates firmware, and make sure stuff like screensaver and sleepmode is disabled. should take a couple of minutes to do.
Restart computer, open my computer. Right click on A05 drive and loooook at properties. It'll tell u new firmware update.
