networking problem

[Chapre]

Hi, I'm using vizard 4. I have a problem with networking with my computer, I use a networking script similiar to the one in vizard tutorial server/client; here's the error I'm getting:
Traceback (most recent call last):
File "C:\Program Files (x86)\WorldViz\Vizard4\python\viz.py", line 8750, in _decodeNetworkPacket
return NetworkEvent( cPickle.loads(p) , port , address )
cPickle.UnpicklingError: A load persistent id instruction was encountered,
but no persistent_load function was specified.
** ERROR: Received invalid network packet

When I run the same script with other computers, I get no errors

Make sure each of the networked machines is updated to the latest version of Vizard. Do you still get this error?

For anyone else with this problem, I had this problem, then I updated to 4.03.0135. Now everything works. It appears that version 4.00.0275 (May 20, 2011) was when raw networking was introduced. This is the first version after Beta 2. hth
