Graphiccard error

Hello
I`ve suddenly (since today) a Error when I want to start SL.
the funny thing is I play since longer here yet, today too.
But now suddenly it says:
"SL is unable because your videocard drivers are outof date or unsupportet.Please make sure you have the latest version of your driver. If you contuine to recieve this message please contact customer Service".
I`ve a GForce 6600 and yes the actual drivers too. Other programs runs fine still.

Ah and I tried a reinstallation too.

The only thing is, that I experimented a bit with the Graficcard Options to make a better looking Picture on screen.

An Idea what this is, and how I can slove it?

Hmm... I think I've read there is a command-line option you can add to your Second Life shortcut to make that message go away. I THINK it's -probe.

May try looking this up in the knowledge base.

Ah I found it. It's '-noprobe'. Here are some steps I wrote for a friend to create a new desktop shortcut with the command line option (I'm assuming you're running Windows):

1. Browse into the SecondLife folder on your hard drive in My Computer.
2. Hold down ALT while dragging SecondLife.exe to your desktop. This will create a shortcut to Secondlife.exe, not copy/move the file. (You'll know you're doing it right when you see a li'l arrow by the SecondLife icon while you're dragging it.)
3. Right-click the new shortcut, and click Properties. The 'Target' field will be automatically selected.
4. Press END on your keyboard.
5. Type one space, followed by: -noprobe
6. Click OK.

also try changing your video card options. If you turn certain things on or off in your video card, it can result in that message.
