Fixed! yes.. I downloaded windows XP Suyin driver
..i think version 2. something(i hope i could find the source url again)..just googled around and find a version for XP 2. something and run it..please do not download this kind of driver
from CNET because it does not have any Camera setup..i mean the "Acer Crystal Eye Webcam.exe".. does not exist.After the installation of Suyin XP(2--)restart ..then right click the (Acer Crystal Eye Webcam.exe) Properties>Compatibility..below the tab :
Run this program in compatibility mode for :
Windows XP SP3.
it now works.no freeze.no error.
