Can't restore with nero

I use to have Win 2000 Pro. and made backups with nero demo version, so that I could restore to xp. After upgrading to xp and own an OEM nero I can’t restore because it show an unrecognize data or I have no licence to open this files. What am I going to do to open the folders which are on a cd rw. How come the oem nero smart is different, because I noticed that under copy and backup there are only two items : copy disc - burn image to disc, where is the restore and backup icon like I use to have in the demo version?
