data call failure : error code 67

[peepeesea]

i have searched and cant find an answer to this issue for the evo. in the user manual is clearly states (page 147) you can USB tether the phone to share the data connection. however, when i do this i get this error message:

data call failure
error code 67. registration failure. your PCS vision username and/or password may be incorrect. please try again

i do have HTC Sync installed. where do i get the user name and password it wants and where do i enter it in the phone?

sorry for the noobieness of my issue.
