It is not necessary to close our cd's with clonecd, because the purpose of clonecd is to clone a cd
so that you get a perfect copy of the original. Why our cd's will not play is very strange
,
I have a few questions
1 - does this problem appears with all the cd's you burned? ,
2 - what kind of a cd is it? and
3 - what version do you use of clonecd? (is your burner supported?)
