you can also try to reload the router...

not sure if this is the case, but if you are configuring the serial subinterface for Frame Relay as point-to-point, you have to reload the router to change it to multilink - even if you use 'no interface ...' command

i know that this is a different situation, but my point is that reload can help sometimes if you can't get rid of some configuration :)
