with alot of other links in it. Disregard the first post since it has nothing to do with your problem, but some things in my answers will maybe help. Especially the things about the Command promth in both the first and second reply, if the unlocker doesn't work

Also registry cleaners are very useful when tryind to get rid of stuff

also the link I posted to a tread LOTR gathered might give you answers

There is no need for you to go visit Daniweb since you don't post in detail. The only thing you will achieve is getting banned or no answer
