In my opinion, there must be something conflicting between the software you are using...I mean, if you have CloneCD and Nero installed on the same HD, they could conflict between them....it happened to me with Nero ver.4.0.0.9 and CloneCD, so since then I've installed them on different partitions of my HDD. Furthermore, to make clonecd work and have a perfect backup of your games, I've seen that millionaire uses a safedisc and safedisc2 protection...so if you have te game with the latest sd2, only a LiteOn 24102b burner will perfectly backup it, 'cause of the supported "correct EFM encoding" (check the Elby site)...if anything of this can help you, I really don't know what to suggest if only to reinstall your O.S.....but this is a real "last chance" option.

Hope this can help
