New Vista x64 SP 2 Candidate Realise + Creative web

Hello.
I was with old beta Service Pack 2 "133" - Studio1535 and Vista X64.
Before 2-3 days updated without any problem to new Beta version "286" Candidate Realize.
All was Ok, till today.
I made conference Skype call with my father and mother.
But the cam just didn't start.
I reinstalled my skype, my creative new video drivers, my video card driver.
Note: after reinstalled creative driver I got my cam to work once and after nothing "no screen from cab or light"!
Well I uninstalled both Skype,Video driver,Cam driver.
I installed new Skype,new Video Driver and I made successful conference call with video.No problem.
Before 30 minutes I dedicated to install creative web cam driver again (old version) and immediately after the install I had the same problem.
The Cam worked once (on Skype Video Test) and after nothing.
I uninstalled Creative video driver again and everything is OK!
Creative Driver for webcam is not very important, in fact the cam is integrated and it is not very good (good enough for skype),and I can use it with standard MS driver!
But with old Bet SP 133 all was ok!
So I guess the new SP is the reason/made for this problem.

Sorry for my bad English!
Just want to warn you about this problem.
