try going to My Documents\San Andreas User Files\
and remove gta_sa.set file
notice: this will remove all settings and single player key binds (should not touch mta binds)
start freeroam resource - you can get your current position with it. or you can put some object in map editor and get it coords.
expecting us to do it isn't good idea.
i had same troubles when i was importing custom objects to vice city (single, not mta).
it looks like some gta engine bug with custom objects dunno if this is fixable.
we are not fulfilling requests.
everything you need is here http://lua-users.org/wiki/StringLibraryTutorial (you need to know basics of mta lua too)
also - this won't work. mta does not support unicode yet!
