Here is what works guys. BTC helped me out and this is what he instructed and I verified it works.
Couple things to check. Make sure you have loaded the DCD USCC Carrier.cab, this should hopefully restore the ability to run #778. If not, browse to the windows folder and run EPST.exe.
Choose edit, enter your SPC code. Go to the Security tab, and then there should be 4 lines listed, the first two are EVDO login and password (labeled HDR) and the 2nd set are your 1X login and password.
The HDR login and password should be
YourESN@uscc.net and YourESN for the password.
your esn should be in hex and in caps, i.e.
A1B2C3D4@uscc.net, and then the same for the password but without the @uscc.net.
The 2nd set should be yourphone#@uscc.net and yourphone# as the password, i.e.
6411234567@uscc.net and 6411234567
