I started amazing charts this am from an exam room computer and it couldn't find the database. (Running Win XP and Windows 7 peer to peer ). Apparently there have been a lot of Windows Updates this week and they are wrecking havoc. People are complaining a lot on twitter.
Anyway, problem was solved by rebooting the router and restarting the machines. Just thought I would post this here. If you are having trouble try this before calling amazing charts support.
