FAQ for Port Listener v1.03

I get an error "Address already in use", why?

You might get this error:

Error 10048 in function Bind
Address already in use.

This error will occur if there is already a process that is listening on the port you have tried to use. The fix is to locate the process using the port and shut it down, then you can run our utility to get 100% access to the port.
