You might need to load the hive offline to get rid of the actual keys by the way. Securerom is notorious for loading what your computer thinks is corrupted keys so that you cannot modify them and replay games that have 30 day trials for example.
THere are also some apps that may be able to get rid of the keys, but I have never used them. I've seen one or two listed however at some time in the past, but can't remember their names. You need a reg cleaner that fixes corruption - that should do the trick.
Just my little tidbits to throw into the ring.

PS. If you load the hive offline and have MCE 2005, set the legacy 2004 bit to 1 so that you can connect to a domain if you feel the need.
