[cvsnt] locking conflict

[Fernando G. Filas]

Hello, I'm new in CVS and I'm receiving an error message trying to make
something with the server.
I have been working without any problems for 5 months. It just happened this
week.

This is the error:
cvs diff Fuentes\Fdetlnk.pas (in directory C:\Sistemas\Neurus\Neurus\)
cvs server: [09:24:42] waiting for Unknown User's lock in
D:/cvsrepo/Neurus/Neurus/Fuentes

More Info:
I'm the only user on this project (Neurus)
CVSNT: 1.11.1.3 (Build 57j) on WNT4.0 Server
WinCVS: 1.3.8.1 Beta 8 (Buiild 1) on WNT4.0 WorkStation

I will appreciate your help
FF.
