Hello, I have the exact same problem.
The VST-Path is set to my default one, where all my other VSTs are.
I just checked and Windows says my graphic card driver is up to date.
I already reinstalled it a few times, even tried the older version (2.something) but always the same problem.
I'm using Windows 8.1, 64 bit.
The program itself seems to work.
It's playing sounds when I press keys, and when I click on buttons and fields they also seem to do stuff.
The only problem is, that the GUI is a mess, and I have no idea what I even am clicking on.
I'd really appreciate if someone could help me getting it to work.
