I was able to authenticate and download the 1300 megabyte installation, but then the application crashed.
I closed it and reopened it and now it is stuck in an infinite "loading" mode.
Should I uninstall the downloader and reinstall it again?

Once the download of the missing assets is complete, the downloader restart on the full game.
New downloaded assets needs to compile before the game.
Regarding your device, it can takes some time (usually ~ 10min).
That's a one time operation and next start will be a lot faster.
Patience is the key here. Sorry :/
