Hmm.... real strange stuff.
Can you log on as someone else and try again? I know you're supposed to have admin privileges but maybe your user account has become.... corrupted? Event ID 1000 is a pretty strange error to be getting for sure, we see them at work related to GPO problems.....
If there is no one else to log in as you may have to go create a new user account with admin access and then try that one, and then see what happens with HOI... give it a try, and let us know!
