FS-Products will be continually updating the base program. All current owners of a kACARSII system can request updates to their system. To determine if your application needs an update you can look at the about me page. There will be a version number for the kACARSII Library. If this version is different from the current version please contact me and I will update your system.
The application version may not match the current kACARSII version. This is by design as the version number of a kACARSII custom is specific to that application. The important version for updating is the kACARSII Library version.
