Renamed Account Folder - Data Lost

I'm trying to set up some accounts on my XPSP3 system. I have some accounts set up, but wanted to change some names. I know that if I change an account name, the directory name stays the same, and I didn't want to get confused later on if I was ever doing some stuff on that directory level.I used this page to copy the settings from my account (named "Main") to a new account named "Admin". I had problems getting access to the folder while in the 3rd account, so followed the instructions here to gain access. Once I got it copied, I loaded Admin and found it looked exactly like Main, which is what I wanted.But then, I went into Main and most everything was gone, and XP was acting as if it was a brand new account. I then went into Documents and Settings and found there were now TWO Main accounts. "Main" and "Main.DARKSIDE" (DARKSIDE is the "full computer name" found in System Properties). I can tell by the directory sizes that Main is the fresh, new account I see in my account list and Main.DARKSIDE appears to be my original Main account (being over 6GB in size).
