Problem with internet sharing on WM 6.1

[Himmad]

So I am trying to use internet sharing on wm 6.1, and it just isnt working.

When I load it now, it just says PC connection now, and doesnt say Network connection anymore to choose Sprint PCS or Phone As Modem.

When i hit connect it says data call failure, with error code of 67. then goes to say the remote party has ended the connection.

I have installed the cab which is supposed to make it work, but doesnt work. I have also tried to load a website first then hit connect but I am still getting the error.
