I was trying to dowload updates for my HD-cx500u2 drivestation but everytime I enter my serial number it says its invalid :-(
I have experienced a similar frustration with the Linkstation Live LS-CH1.0TL-US. The serial number is always invalid. Others were told to go to the appropriate world region website. My unit is North American (-US in the model number) and the serial number is deemed invalid.
It looks like Buffalo Tech has a problem with this web interface. Too bad, I like the Buffalo products and am a bit disappointed in this failure.
