i deleted the script.ini file, it was blank anyway, every now and then i check to see if that file is there, as some trojans/backdoors use that script, my mirc works fine for now, i re-installed windows xp pro (hmm might be another os issue as to why they unload, never had probs when i had win98 se) 2 weeks ago and had no scripts un-install themselves (yet)
