[Doug2k4]

A couple days ago i burnt all my need for speed most wanted files aka mdf and mds's well i made them into iso's so they go onto the cd. then i deleted all the mdf and mds files. But now when i try to make a mdf and mds file out of cd 1 there's too much error's that come up when trying in alcohol 120 like read disc examanation error and disc read errors so of course when i try safedisk or anything program to run the damn game it doesnt run just gives me a dbtmp error or says plz insert cd i uninstalled now but is there anyway i can fix this.
