I am having an error each time I click on any fixture in the project. It tells me that it could not load the file or assembly. I only used the luminaire finder to bring these into my project. What could have gone wrong here? All the fixtures are from the same producer.

Here are the fixtures that were generally used:
RZB, ARELO, 901702.002
RZB, KALEEA BASIC, 312558.002.1
RZB, SIDELITE ECO, 312273.002.1.790

When reloading dialux EVO it fixed this issue for me but I'm still interested in what could have been the cause of this.
