Hi, we have detected that some presets produced by VIZPARK were facing license issues and that might lead to unwanted behaviour of the plugin.
People from VIZPARK are informed about that problem and as far as we know, they already have reworked all affected files. Most probably, you've downloaded your files before that update.
Please contact directly with VIZPARK
regarding that problem. They'll provide you correct files ASAP. Hope, you'll get working models soon and if there will be anything more we can help you with, please let us know.
