Damn technology

I love my new toy -from yesterday's blip- but apparently my computer doesn't like it quite so much. I'm not exactly sure why but my computer doesn't recognise it when it's attached...
...it charges, but I can't access any of the data...
... it works on Laura's computer so it's not the watch...
...and my ipod connects so it's not the USB port...

...I'll see if Garmin support have any ideas.
