I cant see any error in that script.. but you are shure u dont trying to run it in another version of mirc then what its writed for? and if i were you i would get another script.. that script looks big to me, it only give you som system info, and still its huge, you can do the same thing with only half of the code.. so look at
www.mircscripts.org .. then try some of the "addons" there.
