I have tried and tried to make a backup copy of WC3 with no luck. I have tried Clonecd with Clonyxxl, Nero, nothing would work. While I was on the Clonecd board a poster had a url to
http://www.alcohol-software.com/. It worked first try. I have a 24x8x8x8 toshiba reader in my laptop and a Liteon 24x USB 2.0 burner. I never had a problem creating a cd. I could always do an install form the burned copy however it would not play the game. If I put the original back in I was in business.
Dont know why it worked or what is different but it did. Now I can put the original away and hit the road without worry.
