The installer should save the current configuration for you in a registry dump file. It will prompt you to browse for a file location (Otherwise it will choose it's default, which I believe is in the WinGate folder).

The easiest option for you would probably be to do a manual dump of your registry (HKEY_LOCAL_MACHINE\Software\Qbik Software\WinGate)

Once you have purchased a license, it's generally for life.
