Problem starting KDE on CygWin

Hi,

I'm trying to install KDE 3.4 on CygWin. I've installed all the need packages, rebased and done
every step mentioned on readme. When I try to start up KDE, I get a black screen and the following
message on terminal:

WARNING: Problem deleting stale lockfile /opt/kde3.4/home/share/config/kpersonal
izerrc.lock

I've tried to delete this file, but nothing happens, I still receive the same message. What
can I do?

Thanks,

Thiago Takehara
