You can check if there any Updates for the Slider and for the Visual Editor. Just start the SLIDER REVOLUTION Backend Module in your TYPO3 Backend and look for the "Plugin Updates" section on the main screen. You can press "Check Updates" for the Slider and the Visual Editor.
If there are any updates available, just press the update button for the Slider Plugin and/or the Visual Editor. Please clear the TYPO3 Cache in Install Tool after this changes.
