I'm really sorry you've been running into so many issues John. Have you looked at the new manual yet for connecting the companion to the tablet? I put instructions in there for how to set it up.
Having said that, you absolutely do not want to use USB to connect the two. You need to tap the Wi-Fi symbol on the tablet sync screen, and you need to go to Connection->Connect Using USB on the companion and make sure that option is NOT checked. Once you are connecting with wifi, you should at least see the popup window. The very first thing you should do is ensure that you either don't have anti-virus software running or disable the firewall component. Also ensure that Windows Firewall is not blocking MobileSheetsCompanion in Windows. If none of that helps, try rebooting your router, as this can fix some odd issues.
