I know of a repair method but it requires a full version of the OS (the retail version) and is not something I can write in this small box. Also, most folk have restore DVDs so again, the repair I know of can't be done with that.
Let's hope that some one has come up with and easier repair for this nasty. This one was the first that I couldn't find a tool to cure it with. We knew that would happen as if you damage the OS enough, you have to consider repairs exceed what tools we have on hand. That is, the repair I know of requires the installed OS be the full retail version. Let's hope someone somewhere has better news.
