"As stated, I'm able to connect to GHLCC but all my settings and connections are gone."

- What do you mean by this? If you are able to connect to a GHL device via GCC, then you are selecting a device from the connections list and connecting to it. GCC does not store your device settings, these are stored within the GHL device itself. Only the list of device connections are stored in GCC, nothing else.

If you need to make a new connection, do this:
1. Click on ADMINISTRATE
2. Click NEW
3. Select the device for which you want to create a connection for.
4. If this will be a USB connection, set the connection type to RS232/USB. If this will be a LAN/WiFi connection, set the connection type to NETWORK.
5. If USB connection, set COM to AUTO. If LAN/WiFi, enter the IP address of the device into the HOST field.
6. Click SAVE, then CLOSE, and the newly made connection should now be listed for you to connect to it.
