HDlink Serial Number

Ok, I should have kept all packaging, but I didn't. I didn't realize I need this to get the software. So my question is how do I find the serial number of my device without it? Is there a way I can plug it into my computer and get the SN digitally?

Also-Why oh Why doesn't BMD place a simple sticker on the device with the SN if it is so damn important? I won't buy another HDlink just so I can get the SN. I'll switch brands before I do that.
