p servers not working

anyone knows why p servers dont work for me after last file update? it just open menu where i select server for 1 second and than close kalonline

well its possibly corrupt files for the one server. or maybe your virus protection doesnt like kocp.

looks like a error in any dat
inform the admin

i think something block it i only have spybot s&d and nod32...and firewall (windows)...does anyone know how do i set permissions to kalonline at those
