try to look inside map and effects folder sa loob ng SF folder mo. baka may map at effects sila na nilagay dyaan to hack SF. yung effects 4 lang then yun map 10 lang ang files as of last check. copy and paste na lang the files in effects and map folder sa mga working mo. no need to re-install, matagal kasi ulit ka patch. pag wala pa din, try to compare the files in the first level after clicking SF folder. pag same, no choice but to re-install.
