nahhh ... lol ... my mistake
i put the 1024_768 in the wrong folder ...
i didnt replace the original files just made new ones to use
with mod enabler because he mades backups of them so if i need
them again i just have to disable the mod in question
works fine now
thanks
afterall ... with the right instructions editing the files is not so bad
P.S. : i dont seem to find the Boardinstrumente mod in the download section is it under another name ?
