Acer crystal eye webcam not working?

Well this is what happened, A few weeks ago i was going onto my acer crystal eye webcam to take a few photos and i found out it was broke, there where lines down the webcam, i discovered it was cracked, so i sent it away for a repair, When i got it back i went onto the crystal eye webcam and it said "No video capture device was detected on your device", Ive tryed everything from re-installing it and downloading drivers but nothing worked! Could someone please help!
