Trying to connect my LG phone to laptop to use data service

I have a LG UX 5000 phone and the LG data tools kit. My laptop sees the phone just fine and I can set up a connection to use the data service. It is enabled on the phone. But when it tries to connect it tells me the user name and password are incorrect. They tell me they do not support this but I know it can be done, just not sure if I'm using the correct numbers to initiate this connection. Here is what I have it set at.

Phone number to dial: #777
Username: my 10 digit phone number
Passsword: my 10 digit phone number

any help would be much appreciated, thanks.!!
