So I just got the JDK for my computer so I could do some plugin writing. I navigated my own way to the link so I know it's correct. The problem is, my Windows 8 Screen brightness Hotkeys don't work anymore. The bar shows up but doesn't move. Manually adjusting does not work either. I've already tried the old 'Update your drivers' trick, even reloading the old driver fails to fix this issue.
