Did you even try to read my previous post here? No, you don't need to redo your preset when new version is out, you can always use the same! Which version of nLite are you using? Try with latest version if don't have it. And if still does not work, I suppose you are doing slipstream under Vista. Although nLite should fix this problem, for someone fix does not work, so you'll have to slipstream under XP as host, or try to run nLite in compatibility mode in Vista. First, upgrade your nLite to latest version. Second, upload your preset. Third, try to create ISO with nLite and to burn it with some burning software and use lower speed when burning. Cheers
