RS View 32 project not communicating with PLC

I copied one project from one computer to another computer.I configured RS linx software,but it is not communicating with PLC.I observed all configurations are same as the other project which i copied,Any body please advise me how we can communicate a RS view 32 project just copied from one computer to another computer

It's been a while, but the communication may be also using DDE/OPC topics not existing in the new machine. Have you looked at RSLinx DDE/OPC topic configuration in the old versus the new?

What Okie says plus go into the project tree and make sure the Nodes and the Channels are set up the same on both computers

Thanks...i did that..now it is working
