You have not provided any system information or other details liek the exact error message or your exact path, so this sin't going anywhere.
Thanks for replying Mylenium,
I am on Mac OSX 10.8.5 and the path that i changed to was applications/maxon/R15/cinema4d app.
I am away from the computer that has the program installed so i cant retrieve the exact error message but it was something very similar to "Alert: cineware render connection failed"
If you need the exact error message i will be in front of my computer monday and will provide it then but i am very grateful for any help that you can give and for your time.
If merely the connection fails, try another TCP port under the "options" in Cineware. If that doesn't help, you have to dig into your system's network configuration/ firewall. Something is blocking communication of the processes.
