The USBClient installer now creates a new Startup shortcut, unlike the previous WinRAR updates
(before 1.5.2.1). In this case, there may be two USBClients running, one doing recording and the
other receiving the CTI information, or both may have tried to start and the one failed to open
the network, even though the other is not currently running.
Please check that there is only one startup icon and check both "All Users" and the current user's
Startup folders. Also check for two copies of the USBClient running. Afterwards, restart the USBClient
to ensure it managed to open the network ports.
ClientState = 0 in the INI file is VOX mode. It means that CTI information is not coming through
to the USBClient.
ClientState should be 3 for full CTI mode.
