user name password change

[Ned Granic]

Hi all,

I plaied with the passwd command with the -e option while being loged in as root and therefore messed up my forgotten password for my user name -- the one I picked while installing the debian.
Now when I log in with my user name (not as root) and password, it kicks me out by saying my user name is not a command.

How do I fix the problem?

Many thanks in advance!
Ned
