I seem to have a problem with b21 that nobody else is having. When I run the game, I get two error messages.

First there's "Unable to set specified graphics mode because: Unable to find a suitable graphics driver! Now trying to default back to VGA..."

When I click OK to acknowledge that, it coughs up, "Unable to set any graphics mode because Unable to find a suitable graphics driver!"

And that's all. I never even get to the blargling load screen. I've tried uninstalling b21 and reinstalling, to no effect. Same message.

This may have something to do with the boneheaded way I initially installed B21. But the funny thing is, this didn't happen when I did that. It happened after I decided to do it the "proper" way: uninstalled the b20-b21 mess, and then did a clean new install of b21. So I'm now on my 3rd install of b21. Do I need to lather, rinse and repeat? Any suggestions, anyone?

[Edit: My video drivers are up to date. I tried uninstalling b21 again and installing b20, and I get the second message about not being able to find a graphics driver, and no game. Wah.]

actualy your problem isn't with build 21 it's that you have an outdated graphic driver for your computer. to fix this you can look online for a graphic driver update. hope that helped

Downloaded all new drivers straight off the ATI website. Still the same error. Thanks anyway.

Apologies for bumping this, but I'd really like to hear any thoughts anyone has about what's going on here. Now B20 is giving me the same messages.

Try rebooting your computer.

What resolution is your computer running at?

Definitely rebooted my machine a few times since the problem started.

1440x900. The game was initially trying to run at 640x480. I edited the settings.ini to try other resolutions, 1024x768, 1440x900, same result. Also doesn't seem to make a difference if Fullscreen is 0 or 1.

Try running it with your resolution at something more conventional, like 1024x768.

Well, you led me indirectly to the problem. I tried to change my desktop rez and found myself locked out of a bunch of control panel functions. Googled the error message and found that it was caused by Comodo Firewall, which seems to disable functionalities and inveigle itself deeply into the OS in the name of security. (Insert tart analogy about our governments.) Uninstalled that, control panel and Cortex Command now work great. Hurray!

Thanks for your help, TrouserDemon. And if anyone else gets this error message, uninstall Comodo Firewall until they make it a bit less bloody aggressive.

Yeah, makes sense, when CC tried to change your resolution to what it used, your firewall blocked it.
