[FreeNX-kNX] New 1.5 Windows Client: How to use?

[hc]

Hi,

last week I installed the latest freeNX-packages released for SUSE 
(NX-1.5.0-9.1.i586.rpm, FreeNX-0.4.1-1.1.i586.rpm from 
http://www.mirrors.net.ar/pub/suse/i386/supplementary/X/NX/) on my 
server. It should be based upon the version 1.5 libs and worked fine 
with the "old" Windows client (OpenGL too). Today I tried to use the new 
1.5 Windows client, but it does not work for me (message: "Server not 
installed or NX access disabled"; detail: "204 authentication failed".). 
The public key is correct (it was not affected by the installation, 
nevertheless I put it into the respective directory again). I am 
grateful for any hints on how to get things working.

Best regards,
Hans-Christian
