~~ Instructions ~~
First off, download the 5.4.8 client if you do not have it yet HERE! (Optional)
Make sure you download all the required files, unzip it in a new folder and extract all the data files to the data folder! (Maps, vmaps, mmaps, dbc, db2)
Your folder should be looking like this.
After your worldserver is up type ".account create name password" and ".acc set gmlevel accname 3 -1"
-- Sorry for the weird picture size, but seems like it's the default size, so I can't really fix it without reworking the thread-design fully.
