Phone as modem issue

[robbie2883]

ok, i'm stumped. the other day i setup my phone to connect as modem through usb and data connection. plugged it into the usb port on my laptop, vista installed the divers and everything worked perfect. now two days later we're about to leave on our trip and i go to test it one more time before we leave and it doesn't work now. i check through my connections in the network center and it says it's connected to the phone but local only...no internet. i can't get it to work for anything. any suggestions anyone? sorry for not searching more but we are on the way out the door.

also i can still use the wifi router app to connect but i'd rather use the usb connection.

phone is a htc touch pro using mighty rom
