[FreeNX-kNX] Problem to connect NX Client 3.0 with freenx server 1.4

["José M. Perea"]

Hi to all,

I'm trying to connect my client machine (Windows Vista) with my server 
machine (Ubuntu 6.06).
I'm using FreeNX Server (NXSERVER - Version 1.4.0-45-SVN OS (GPL)) and 
Nomachine NX Client for Window 3.0.0-68 (last version).
When I try to connect, I obtain this log:
