Calkulin FC15 USB Tethering Issue

[itsbotastic]

Does anyone know if USB tethering is working for Calkulin's FC15 rom? I can turn on the function in the settings menu, and even my Windows 7 recognizes that something is trying to connect to the internet, but I'm not getting any internet access.

Also, I get a weird message on my phone when I turn on USB tethering saying that my Sprint ID username/password is incorrect. I've logged into my Spring ID on my phone so I know thats not the case.

Any help would be greatly appreciated!
