Fiddler not capturing traffic from browsers

I've been using Fiddler for quite a while, but all of a sudden it no longer captures internet traffic. I'm on Chrome 29 and Fiddler v4.4.5.1. I've checked all filters and rules and nothing is on. I've deleted my rules file, turned on and off capture traffic, and a few other things with no luck. I even uninstalled and re-installed Fiddler to see if that would help but to no avail.

What am I missing?

[Follow Up]:

• Troubleshoot Filters has no effect.
• I see no activity in the log tab beyond "Fiddler Running..."
• I've tried multiple browsers and none show internet traffic in fiddler
• http://localhost.fiddler:8888/ does not work
• http://127.0.0.1:8888 works and shows the fiddler echo service.

Not sure if this is relevant but I had the same problem with Fiddler after the last update (v2.4.5.0). I turned all filters off but still wasn't picking up any traffic. When I unchecked Use Filters on the filters tab, however, all traffic was picked up as normal. I'm still trying to figure out how I can use filters when just checking Use Filters box causes all traffic to be blocked.
