I suggest checking if the main computer appears in the "Network" pane of Windows Explorer on the client laptop when you first start up in the morning, before trying to log onto AC. This may isolate it as a wireless network issue (can't see the main computer) or an Amazing Charts issue (can access the main computer over the network, but AC can't find the database). From what you have tried, I suspect the latter. I think it would be worth trying a
"Live Chat" with an AC tech person to try to reproduce the problem.
