For those that e-mailed us, I'm hoping to process that batch this weekend. To confirm David's reply, if you clear XBMC's data, then user/pwd will need to be re-entered, yes. HQZone access is advertised as for demonstration purposes only. They should last a while, but as with all 3rd party add-ons and apps, if they take everything offline, we'll not be able to do much beyond recommending alternatives add-ons.
