I almost finished the online workshop but have some problems running multiplayer workshop 25.

I first check boxes client and server in: Options->Preferences
When I run the program (script25.c) I get the following errormessage:
"Malfunction W1527, start as client or server"

when I run the program again but then as a client, I do not get this message, however the client-server connection does not seem to be established. It looks like I'm running two clients instead of a client and a server.

Any one knows what went wrong???? I already checked my version and edition (7.8 commercial edition) so multiplayer should be supported.

check only server for one and check only client for the other, and read more carefuly

Quoting workshop 25:"Start the server first: check both Client and Server, then hit Ok and start the script as usual."

and that is exactly what I did, I started the first engine as a client and a server. The second engine only as a client, but as I said that didn't work.

I also tried Quadraxas suggestion: first check only the server and than only client, but I get exactly the same errormessage when running the server.

Mine works when I checked Client AND Server, that's what it says to do. Maybe there's something about your system settings. I know I had to unblock acknex via my Windows Firewall.
