howdy Cashper and welcome to the forums!

there are a few possibilities.

1. check to make sure your software firewall is allowing keyclone to connect between machines
2. make sure both machines are on the same sub net or have a route between them
3. the port on the destination keyclone changed and you didn't notice (check the titlebar)

if you're still having issues, please let me know.

good luck and welcome to the addiction!
