Hello, When I installed Leopard for the first time yesterday through Erase An Install, everything went great. However, there was a glitch on my part and that was when during the set up, I accidentally made a typo when entering my Apple ID and thus my short user name (the one next to the house) was not what I wanted it to be. Since I could not manually change it, I started a new account and deleted the contents of the old one, which solved the problem. But that started new problems. Now I can't access any of my previous mail on Mail and so many folders on my external drive are locked because I do not have "sufficient access." I tried changing the permissions, and it worked, but there are so many folders with this message, I am wondering if reinstalling would do the trick and solve some of these glitches. If so, how would I do that? Any help would be greatly appreciated. Thanks!
