can't connect to the internet using Sierra Wireless Watcher/AT&T card

ack, help! I've had this laptop (MacBook) since June and when I got it I also got an AT&T wireless USB device that I use most of the time. And it has worked until today.

When I open up Sierra Wireless Watcher and click connect, it hangs for a minute and then says 'disconnecting', then 'could not negotiate a connection with the remote PPP server, check your settings and try again'.

I've tried several different things in network preferences, I've verified disk, restarted and even used Onyx to clean things out, it did nothing to help the situation.

What should I do?
