L2J Server

Hello i wanna create my own L2j server now just for test , i have db already in mysql , when i click on register game server, it does work but it switches off immediately and it doesnt create hexid.txt... where is the problem?
everything is set, however something is wrong and i cannot run it

make sure your login server is connected to the database with full write/delete/modify privleges...
then you can run gertistergamserver.bat

try Gsregister.exe
