unable to start game Thread - Bloody Trapland

OkAY, when I try this game using demo version, it works. But when I bought this game, and inatall the. Exe file(74mb)
it syas not found graphic drivers and unable to install graphic drivers.
But when I install, it installed me the driver. How can I fix this?

Ps. I install demo ver.using desura

did you also download the full version from desura? and did you try and run as administrator? you can also:
''try running the game with (or without) the client. Either install the standalone or go to you're Desura/common -folder and launch the bloody trapland.exe directly.''
also try doing some of this:

• Run game as administrator
  Goto "C:\Program Files (x86)\Desura\Common\Bloody Trapland", rightclick "Bloody Trapland.exe" and choose "Run as administrator".
• Install/repair both XNA 4.0 and .Net 4.0
• Delete your save/settings folder: C:\Users\*username* \AppData\Roaming\Bloody Trapland
• If installing from Desuras client, remove this folder: "C:\Program Files (x86)\Desura\Cache", then re-download the game.
• Reinstall game''

Yes.. Yes.. Still not working. It always says no suitable graphic card found, unable to create graphic device. I download the installer exe for full version from desura.

And when I first timw playing the demo, it runs. But after I install full version it keeps showing this error

well try this then: (re)install the latest NVIDIA graphic card drivers and choose "Custom (Advanced)" setup and to check "Perform a clean installation".
