All I've done is "install" it. these are the problems I've encountered in a clean state with a local server with no mods.
I don't know what to tell you. As far as other processes for the server thing, There aren't any, the bat runs, the server opens for a second and then closes.
There may be some kind of issue that is my fault that I'm unaware of. But to me, a clean install of both fivereborn and gta as well as the server is broken.
