Updated from CCC 12.4 - 12.6, broke my dual monitor setup

I updated my AMD drivers and CCC from 12.4 - 12.6 and now CCC won't detect my second display.

I have a Radeon HD 6850 and an onboard HD 4250. My primary monitor is hooked up to the 6850, and my
second display is hooked up to the onboard 4250. Before I updated, this worked perfectly. I would just go
into CCC and click "Detect Displays" and then I could use a multi monitor setup.

Ever since this morning though, it doesn't detect it anymore.

Additional information:

64 bit version of Windows 7

The package I downloaded was "12-6_vista_win7_64_dd_ccc"
so it's definitely the 64 bit driver.

In my device manager for the 4250 it says: "Windows has stopped
this device because it has reported problems. (Code 43)"

Windows also says the driver for the 6850 is: 8.980.0.0
but the driver for the 4250 is: 8.961.0.0

Not sure if that relates to anything.
Thanks for reading!

Uninstall the drivers, run drive sweeper then try reinstalling. If that doesnt fix it then do it again and go back to 12.4.

One question, why are you using the onboard video? I dont think you can crossfire a 6850 with an onboard 4 series, and a 6850 alone should be enough to run more than one monitor, so why use the onboard at all?

The problem is that the new 12.6 doesn't support the 4000 series anymore.
I'm having a similar problem and looking for a solution, for now I went back to 12.4.

Personally, I would just disable the 4250 in the bios and just use the 6850 for both monitors
