1) download the latest L# Loader from here, and create an entirely new folder seperate from the first version of the loader: http://bit.ly/1qS18Ul
2) download this edited config file: https://dl.dropboxusercontent.com/u/45206154/config.xml (it's no longer necessary to replace any user location, this will work on its own)
3) place this config file into the new L# loader folder
4) you should now see something like this when you open the loader: http://puu.sh/bDjGW/f2c943fff7.png


from here you just tick/untick the desired assemblies you wish to run. you cannot disable the libraries necessary to run the loader, so don't worry about the ones you cannot untick.
in order to update the assemblies, select the first one, and shift click the last one, or select a random assembly and press ctrl+a to select them all, then right click and click "Update and Compile."

depending on how many assemblies you have, this can take a several minutes. you will see the current progress though when it says "updating..." or "error compiled" in which case a log file will be generated letting you know what the error was.

you can modify the hotkeys by going to settings and clicking the current key, and then pressing the key you wish to replace it with. it's sensitive, and doesn't have a very visual indicator that the hotkey is currently being changed. just click it and press the key you wish to replace it with and make sure you don't accidentally hit something else before switching tabs (yes, it's that sensitive.)

you shouldn't run into many problems if you followed these steps closely. this loader does *not* find *new* assemblies. you will have to install these manually. to do this, follow these steps:

1) click on "Install New Assembly"
2) select "Git" and type in the URL of the repository, then hit "Next." this will parse the repository and list the assemblies available to download and install. simply check the assemblies and click "add." you should get a confirmation that the assembly has successfully installed. if not, well, that sucks, it's probably broken, and this guide can't help you with that.
