The screen stays black when I plug in my NewerTech DL adapter.

I'm using version 1.8 (39186). I installed it after installing 10.8 clean on a new SSD. This is a MacBook Pro mid-2009 17".

Every once in a while it flickers but it never shows a screen. A monitor does not appear in the Displays Preferences Arrangement tab.

The display and adapter work with Lion.

I rebooted my MBP today (let the battery run out whoops), and shortly after logging in, I saw my screens (internal and displayport) go black for a second. I've seen that happen before with DisplayLink installed, so I decided to try plugging it in again.

It's working again!
