Hey all I need some help.

I installed windows 8 pro+wmc.After that I installed my drivers(audio,lan,video),after that i launched CCC and it worked then I installed some programs and dosen't work anymore.In task manager MOM.exe and CCC.exe are working and when windows starts it starts CCC but when i click on the icon from start or taskbar or menu(from right click) iI wait 10 second and don't show up.The old drivers dosen't work on windows 8 for video card so i installed the beta 12.11 beta 4.I have all Microsoft Visual C++(2005,2008,2010 all with the necessary update) and the .net farmework(1.1,2.0,2.1,3.5,4.0,4.5 all with the necessary update).I tried the method with driver sweeper to uninstall and reinstall,I don't have in C:\windows\assembly the public key token.What I can do ?
