How do I get a new copy of the setup software?

OK, my system is down and I can't bring it back up.

I changed routers (I upgraded my Internet) but I can't tell my system how to connect to the new router. Normally I would run the software that comes on the USB that is part of the remote, but that USB drive has gotten corrupted. When I plug it into my base station, it says "Setttings not saved". When I plug it into my PC, it says the drive is unusable and offers to format it.

I tried ordering a new remote to see if it would come with new software, but it didn't have a USB drive with it. I've looked for a download, but all I can find is software for a Mac. (I'm on Windows.) I've tried contacting support, but they keep telling me how to change the battery in the remote and how to set the system to home or away.

I just need to be able to run setup again. Otherwise my entire system is effectively down. Is there *any* way to get a copy of it?

Thanks
