Unable to run jar file

[GhostTheDreamWalker]

Hi

Maybe someone can help with this.
I downloaded the stlab v0.3. When I run the jar file I get this error:

I installed the Vox USB-MIDI Driver for Windows 10 from this website before running the jar file:
https://voxamps.com/downloads/

I'm not sure if I'm missing something or did something wrong.

Here is the stlab.log that gets generated when I ran the jar file:

Any advice or any information that can point me in a direction would be greatly appreciated.
