Still getting the error when trying to use the open button. Really weird.. haven't installed anything new since original installation of filebot (which I love btw). Just started happening.
If you click the Load Button, then FileBot will open the Windows File Dialog, which means any changes to Windows can potentially break things there. Since Windows changes all the time, somehow something changed now causes this issue. But it doesn't seem to happen to anybody else, so investigating the issue would take dozens of hours and possibly not lead to any useful solutions since I can't fix Windows.

Does filebot use javaw.exe? If so, maybe I should confirm that it's physically where it should be?
The UI wouldn't be visible if the javaw process wasn't working and running it. The error message just says javaw because the javaw (FileBot) process is communicating with Windows and somehow something doesn't work, and so Windows pops up a warning that javaw isn't working somehow.

TL;DR No idea. Just use drag-n-drop instead. File Dialogs are a rather inefficient way of selecting files anyway.
