Hi,
I‘m afraid, that currently there‘s no automatic detection of the current network, but this parameter "LicservHost" is stored under following keys:
[HKEY_LOCAL_MACHINE\SOFTWARE\Itoo Software\Forest Pack Pro]
[HKEY_LOCAL_MACHINE\SOFTWARE\Itoo Software\RailClone Pro]
and changing this value, for example by „importing“ prepared .reg files might be an option for you.
Best regards,
