Airline, NERDTree not loading

[sagnibak]

I have a rather minimal plugin setup currently, but for some reason, NERDTree and Airline-vim don't load until I run PlugInstall. Please note that Jedi-vim is loading before running PlugInstall. I am a little new to Vim. Any help is appreciated.

(Also, I don't know what the block of code at the beginning of my .gvimrc file is doing. I got it from here.)

The configuration should be in .vimrc not in .gvimrc.
