.Map :: MoHAA Mapping

When i make a script and save it as mymapsname.scr it is turned into a screen saver application. Would this have any effect on MOHAA being able to read it?

I have also been having problems with setting up a German firing an mg42, and when that german dies another one is spawned, i followed the level editing part of it from this sites tutorial and i put this in for the script:

main
exec global/loadout.scr maps/mg42.scr
exec global/ai.scr

level waittill prespawn

level waittill spawn

$mg42 thread global/mg42_active.scr::mg42
$player item weapons/m1_garand.tik

end

When i get into the game nothing happens.
Can anyone help and if possible design a example map, with a script. Thanks

It does not turn into a screensaver, windows just thinks it is. So you have to open it maually into yous text editor, because if you double-click it windows thinks its a screensaver and you get an error. But its still a text file.
