VectorayGen Version 1.04.1 Broken Viewport

[MystaraCorvus]

Good Evening,

I just recently started to work with Vector Fields and I wanted to get more serious. I found your tool and it does look pretty amazing.
After installing the Test Version, I sadly can't get the view port to work. I won't display any particles or any arrows. Instead, I see a distorted white dot that is the same dot as the connection between nodes. When I move the nodes, the dot moves with them within the Viewport.

One other thing is that I can't get the Viewport docked again.

I am considering buying VectorayGen, but it would be extremely sad, if the tool is not working.

Sincerely,
Felix Schmidt
