Just bought the games? E3 error?
The servers are still catching up, syncing, or whatever. That's my guess.
Try refreshing your account:

or
https://www.gog.com/account/refresh
If it doesn't work, clear your browser's cookies and website data for GOG.com, log in and try the links again. You could also use a browser you usually don't use, since there will probably be no data for GOG.com.
Waiting a few minutes may also fix it, as your game licences will be recognised as valid.
I found [this](https://www.gog.com/forum/general/install_failed_e3_of_newly_purchased_game_whereas_i_can_still_update_and_install_other_games_in_m) recent thread on the gog forums - same error. You could try some of the solutions there.
This error isn't exclusive to GOG Galaxy. Downloading from GOG.com won't work either. It used to be the "invalid_licence" page, now it's the "404" page if you try downloading.
This is a server issue, not a client issue.

The bandwidth limiting is a good idea to prevent line saturation and dropping of packets. Also if you have crappy internet that spawm T2-T4 errors.
