Hi all!
I have exactly the same problem, but the tips you have here didn't help. I even used Microsoft's Fix It tool, that delete the register for me, but it didn't help either.
Every forum have the same tip how to fix it, but it didn't work for me.
I hope you can help me how to fix it.

The document is really important, so can you send me a copy of the answer to my email ? : Clickmember@gmail.com

ps. Sorry for my bad english
