Webcam driver trouble

Hey guys
I need help here
I got this webcam from china few years back i lost the cd for the drivers
I found the drivers from Vimco and everything i needed
i got it to work on windows 7 just few hours ago
but due to issues i had to format again and reinstall windows 7 and now the webcam doesnt work
it says that the driver is working properly but when i open the program all it shows is a white screen
can anyone help me out?
