cant copy using clone ?????

[stanwing]

hey fellas
im new to this game but have been told clone is the main man in copying games etc
ive got a lite on writer and ive checked with clone website and it says its ok.
anyway im trying to do backups of 2 backups namely tweenies and millionaire but when it tries to read the disc it just goes really slow and locks up the pc ive tried using the writer to read instead of my panasonic dvd but still the same.
ive used it for other stuff and its ok so i think its the 2 games as it does exactly the same with nero
anyone help out a newbie
thanks very much
oh im using latest clone
ta
