:loop
start Jazz2.exe
PING 1.1.1.1 -n 1 -w 60000 >NUL
goto loop

this way the batch would start jazz2.exe and then wait 1 minute and start jazz2.exe again, (if there is a jazz2.exe running it wont start it again, but it does not fixes the error messages)

i must find a way so i can close jazz2.exe and then start it (this way we can make a server restart every hour, so if the game crasches you can allways wait for restart).
