Wow, I missed that one. Of course the 4Gb is the problem! We are using a 4Gb card because it was on sale and it was half the price of the 2Gb unit that we initially intended to buy. Much apreciate the tip. Will buy a 2Gb tomorrow and try again. Thanks for the firmware update link. Not sure which version is running now on the 440S but it should be the one that originally came with it so it is high time for an update. Big thanks!
