dell webcam central turning green

 hello all.

i have a dell inspiron 1545 with the integrated webcam run on dell webcam central.

after using some effects on the webcam, everything turned rather green and grainy.

so i uninstalled and reinstalled the webcam (don't even want to go into that), and when i finally got it reinstalled, the same problem was still there.

here are examples of what it looks like:

this is what it used to look like:

as you can see there's bit of a difference. any suggestions would be really helpful, due to the fact that my warranty is up and i cant call dell tech support.

thank you!
