Fog light bulb replacement procedure?

[Pete_89T2]

Ok guys, I must be missing something here... Spent the last half hour trying to free the fog light lens from the bumper to get to the bulb on the passenger side. Took all of about 5 minutes to back out the screw and get that clip on the other side unfastened, which allows me to pull the lens back about 1/2~3/4 of an inch but it won't come out any further so I can access the bulb from the back as the diagram below attached. There's plenty of slack on the cable, but it seems to be hanging up on something on the screw side.
