It works now. Here is what I did to make it work. I executed the Purge and Reinstall. I then downloaded the latest version of Multiplicity on both Primary and Secondary computers. I installed Multiplicity on the Secondary computer first and then the Primary computer. I then chose to always connect with KVM mode. I then changed the advanced settings to always use IP address when connecting to secondary computer. After all these steps I tested copy/paste and it worked. Thank you for your help and for sending the web link for the Multiplicity instructions and how to steps. When the Trial period is over, I can only afford the KVM version of Multiplicity.
I am hoping that there will be a sale on the KVM version.
I am a long time user of Stardock products and have recommended then to many friends and coworkers.
