Trying to get DDO working on a Windows 8.1 laptop. Working fine for me right now on a different Win7 machine.

TurbineLauncher.exe (what the shortcut runs) works fine - put in my username and password, patch, select server - everything good up to that point. But when I click "Play", no game client. The tail of the dndclient.log is:

Code:
000000000.000: Initializing display with title 'Dungeons and Dragons Online'...
000000000.000: Device_WIN32::Init: called.
000000000.000: Device_WIN32::InitDEVICE|  Detected operating system: Windows 7
000000000.000: Failed to start rendering system.
000000000.000: Device_WIN32::Cleanup: called.
So it looks like dndclient.exe is running, then giving up. Things I've tried include putting the exes to run as Admin, and putting them in Win7 compatibility mode.

Anyone already figured this out?
