Need help with blindwrite

I just downloaded Blindwrite (trial version about yesterday) to make a copy of a pc game I have (I am not that sure on how to use it so I tried to make sense of it the best I can) I popped the game in the cd/dvd rom drive and the empty dvd in the cd/dvd writer and pressed copy after a few minutes the process bar was full then all I heard “was we have a problem” and I realized the game wasn’t copied

I would just like to know why is this happening? And what do I have to do to get a working copy( I already ruined 3 blank cds)?

I would also like to know if anyone could give me some pointers or steps on how to use Blindwrite? For example when should I use Copy, Read or Write?
