unable to logon after updating ports collection - Freebsd 7.1 stable

[Roy Stuivenberg]

Hello,

After I completed my Freebsd 7.1 stable, and updated all the ports, I got
prompted with another logonscreen.
Whatever I try, I can't login with my useraccount and even not logon as
root.
This happened severall times now, the only way was to reinstall everything,
and I was hoping to resolve this by completly finish upgrading the ports.
And .. again the same problem.
I'm really hoping to get some answers that will solve this problem, maybe
someone had to deal with this  issue before ??
I will not give up, because Freebsd stole my heart.

Regards,

Roy.
