Dell Webcam Central Problem

Hey guys so having such an annoying problem with my webcam central at the moment.

I decided to try some of the settings and changed the zoom and pan of my webcam, however now every time I try and set it back it automatically zooms back in, and pans to the far corner. 

I've tried uninstalling my webcam drivers and reinstalling them, and reinstalling webcam central but to no avail. I've googled this and only found one other person who had this problem too but the problem was never solved.

Any ideas?

Thanks!
