I've been trying to update the firmware on my ND 2300 on a pc so I can use it with a mac. I got the firmware screen to show up on the device once by pressing the reset and copy buttons, but it vanished before I could start the download process. now I cannot get it to work again. I keep getting "key input error" and a beep. I've been trying for hours and no success. I'm getting to the point where I want to return it because I can't use it if it won't connect to a mac, and it seems to need the firmware update to do that, and I can't get that loaded.

You should be shipping these with the latest firmware! Especially since it's advertised as working with mac. Please help!
