Dear Ruben,
You need to make sure that the version of OptiPerformer is 20. You could download the version from Optiwave’s website.
You may check the “OptiPerformer Features and Operation Description” recording on Optiwave’s YouTube Channel or at Optiwave’s website “https://optiwave.com/?s=OptiPerformer+Features+and+Operation+Description&post_type=video&opti_product_category=&ow-filters=1”
