Mediamonkey doesn't recognise your device?

Give the device a name in Windows Explorer (right-click, properties, type something in the blank box and hit ok).

Mediamonkey seems to have trouble identifying devices without a name - perhaps because it can't tell different devices apart if they're all called "Removable Disk F"?

rwc crowd estimates - i don't buy it

Estimates of only 50k people to both the game and party central? These are implausibly...implausible. It makes much more sense to interpret this as estimation being cut to fit what the transport infrastructure can handle. Thus all involved can claim they're only to blame for mismanaging a specific event rather than comprehensively failing in the years of planning and preparations that have led to this point.
