If you access the official website of the developers, you'll see the following message:
Libronix DLS is deprecated. Development for the LDLS platform stopped with the release of Logos Bible Software 4 and 5 but an archive of old support articles and basic training is available below, but may not be compatible with current computers and operating systems.
As you can see, the application you're using is deprecated and development has been stopped.
