You have received a new set of Glink configuration files. If you install it, you will get a new set of configurations that will replace your current configurations. All your current configurations will be overwritten and lost.
It is possible to export your current configurations by mail. Mail them to yourself as a backup. This can be done from the Menu -> Export Configuration function. You will be asked if you want to include Connect macros (if you have any), before you are taken to the Send Mail function with your configurations attached to the message.
