I am trying to reinstall windows ME on a machine that came with it when it was bought bran new. When i am in the install process and it ask me for the key i type in the key that is on the COA on the computer. It keeps saying the key is invalid. if you call the number on the screen the checked it and said yes the key is good but offered no more help. If anyone knows what i could do to get this to installed please let me know.
