well hi there Swaggie,
i dont think god is a member here... yet,
so here is 1 thing to look for, of you see this at the top of any included script like poker, hangman etc, remove it as it should only be in the MXC.mxl
<?xml version="1.0" standalone="no">
it dont like fancy characters like we add in names and tags etc, thats 1 thing to try...
another is, weather you have the MK4 plugin or not, if you do, you need this line in the MXC.mxl
but if you dont have the MK4 plugin, you do not
need that line in the MXC or it will cause an error.
