It's Fast Tip time.
Are you out of town and having a problem doing an Internet sync with ACT? Some routers will get grumpy with DNS settings or proxies, especially hotels. This will cause the sync to not work. Here's something that might help.
Open a Command prompt - make sure you right click on the Command Prompt and choose Run as Administrator. Then, on the prompt, type in the following:
ipconfig /flushdns
This will clear out your computers "brain" and what it remembers as DNS settings.
