[newbie] kppp pppd died unexpectedly

[yo]

Hi all
I installed Manrake 7.0-2 in mi PC but unfortunately, Is the firths time
I cannot enter
in Internet using de kppp dialog screen.
I have to use linuxconfig to setup my internet account.
Do somebody experienced the same problem, the message is 

pppd daemon died unexpectedly

Even using the "root" account.kppp does not help too much ,

Thanks in advanced
