You can, but then you'll need the source files that I used when I compiled the server, since these are not included in the repack. But if you want, you can download the zip file from Mega, it's 1,5GB. Unpack it to a folder that does not have a long name (to avoid errors during compile). Then edit your worldserver.conf and authserver.conf to specify where the source files are stored. Once everything is in place, go to the "ac" folder, and type: git pull. Do the same in each module folder (or use a script that performs "git pull" from each folder all at once). Now you can go ahead and compile the server. Once that is done, run the servers, and it will automatically import all the updates in to the database.
Paste this in a .bat file that you save in the modules' folder, and run it to update every module in this folder.
