Hi Mandana,
It appears that the USB blaster driver in Quartus II 8.0 has problem. 
It looks like a mistake in the 8.0 release. We should be able to fix the issue in the next release 8.1.
I have attached the driver in Quartus II version 7.2. 
We have tested the attached driver and it works well. 
For driver installation guide, refer to http://www.altera.com/support/software/drivers/dri-index.html
Hope it’s helpful to you!
Regards,
Roger
