Black screen during startup, possible solution.

[Zexel]

Posted on the Bug Report Megathread, but I'm afraid it'll just get ignored and lost there.

For the past 2 weeks I was able to play PW just fine. Took a break from it for a couple of days, tried starting it up today, black screen.

Tried updating Geforce drivers, restarting the laptop. Still doesn't work.

Then remembered my issue playing the Thief games. Pressed Alt+Enter, start menu shows up again.
