Alright, I finally got around to re-making this library. I completely recoded all of the functions using NetRead instead of 39dll this time. I didn't include a demo game this time because this one is extremely easy to use (in my opinion).
All I did was upload the .gml file of scripts you just have to download, open Game Maker, click Scripts > Import scripts and find the file.
Each function has a parameter and return list which should get you on your way, aswell.
You can find the file: http://gamejolt.com/open-source/games/other/gm-achievement-example/1264/
NOTE: Every parameter must be a string.
EDIT: Added GJ_data_check_key() so you can easily check if a key exists.
