I'm trying to use the repair option but it keeps asking for a admin password. >>
Then your title for this thread is misleading.
Try as
spoma suggested. If that doesn't work somehow you must have assigned a password to the Adminstrator account.
You may be able to reset the password using the method
Saltin describes
here. Then again I don't know how borked up things were to begin with that caused you to try a repair, so it may be of no use. This will reset the password back to what you originally chose as the password, so if you are mistaken about not entering a password it's not going to do any good.
