VPCZ2390X Catalyst Control Center stopped working after update

Hello!
I have a problem. I have VPCZ2390X which comes with PMD. I recently updated my drivers through Sony.com, but since then CCC stopped working. The problem is, that after couple connect / disconnect, my PMD video card stops working - I can see that via windows score and via screen resolution (it show only intel HD family).
If I go back to original drivers, CCC works fine. But those drivers are 2011... But how is it possible to update?
I have Windows 7 Professional, I did not re-install my operation system.
I did not install any third party drivers.
Please help.
I already tried clean sweep, driver fusion, etc... CCC only works on original drivers, but not on the update.
Thank you very much!!!

 

May be there is another way to install drivers that will work... It's just - it is really annoying that external video card does not work...
Hope you can help me. May be someone else had this problem, or may be you could help me with clean install.
Thank you again.

 

And now my system thinks that I have AMD 6700HD instead of AMD 6650HD in powermedia dock. And I cannot roll back now. How is it possible to completely uninstall it? And worst of all - I do not have recovery disks available.
Please advise.

 

Have you tried the UnifL drivers? The latest stable version seems to be this:
Catalyst 12.10 WHQL UnifL for AMD+Intel Graphics ← leshcatlabs.net

(there are more recent beta drivers with catalyst 12.11, if you're adventurous, or if the stable driver doesn't fix your issue)

Good luck .
