I have very bad news... I'm afraid my computer has, well, died. None of the USB ports work and thus I have no mouse and no keyboard. It also randomly crashed three times followed by it refusing to start until I shut it down for over an hour.
I have a backup PC, but unfortunately it does not contain the files needed to create the update, and I'm not sure when the problem will be fixed; it may fix itself after a few hours in the powered-down state, I may have to wait until Monday and take it to a technician, who could then take up to a week to fix whatever the problem is. I don't really have the state of mind required for redoing the map from scratch on my back up, so, unless the problem solves itself, the game will have to either be a) suspended or b) another take my place as GM, whether temporarily or permanently.
I'm sorry for the inconvenience... now if you'll excuse me, I'm going to go cry in a corner.
UPDATE: mouse is now working but not keyboard. I have to use the damn onscreen keyboard.
UPDATE 2: Crisis possibly avoided. Both mouse and keyboard now work, after numerous restarts and shifts of the usb connecter to a different usb port. My wireless headphones, however, do not work. I'll jump that hurdle after updating.
