Webcam from Acer Crystal Eye not working

Hello, everyone

Last week, I installed Windows 7 on an Acer Aspire 4530 laptop. My webcam hasn't worked with any of the drivers I've found to make it work with the 7, and I've tried every possible driver. I downloaded the drivers from Acer's website and the device manager shows that the webcam is working fine, but when I go to Skype to install it, I get a "loading" animation. I also get a black screen. Is there any other way to get it to work? Originally, the laptop came with Vista, but when I got it it had a bad version of Windows 7, so I bought a new one, wiped the hard drive, and installed Windows 7 home.
