My proxies won't load into the queue of media encoder

Every time I go to create proxy files, in premiere it says "creating proxies," but when media encoder loads, nothing happens, and none of the files load into the queue. I have the most recent versions of premiere and media encoder. I tried multiple clips from different projects, used custom ingest presets, and I even tried some of the default premiere ingest presets (which I usually wouldn't do because I like to create my own proxy ingest presets) Every time I give it a go, "creating proxies" comes up, media encoder loads, but then nothing happens. 

Does anyone have any advice on what they think could be the problem? Any help would be greatly appreciated. Thanks!
