Updated into Sierra yesterday, and Alfred will not open since. Shortcut key does not work. Opening from Applications does not work. Activity monitor tells me it's running, but even when it's running it doesn't show up in Force Quit Applications. Not sure if it should though. Activity monitor is also telling me it's using 0.0% CPU, but again, maybe it's just such a small application. Tried deleting it and reinstalling it from the app store, but that did not work either. Tried turning off Siri (as my short cut key for Alfred was also OPTION-SPACE), but that didn't work. Haven't seen the same problem around the web, so thought I'd post here. Thanks for any help!
