I too have been having problems for the last 5 days.  I can get authenticated,
but when the programs tries to pull the IP stuff out I get errors up the butt!
I am using OS/2 Merlin beta and had no trouble untile after two weeks of use
and I know that it is not merlin because all of the PPP dialer stuff is the
same from warp, and I have been using warp all summer.
 
But like I said the error is not with authentication it is with the IP
requests, I can give you about twenty pages of error if anyone want them.  But
I dout they do.  I hope that you all get this worked out within the next few
weeks other wise you will have a few unhappy people who will be upset about
having to pay for a service that does not work worth a crap now.
