Problem with XP & User Names

[Nizzle]

Aiight, maybe you guys didn't understand my problem. My old user name had as many capabilities as the "OWNER" name. Now, when my computer messed up a while back.. I rebooted it and decided to keep the files from my old User Name. However, this name had a password. Whenever I try to get into these files, I can't. It doesn't even give me the option of entering a password. I tried creating another user name with the same name as before but all it does is add .HOME to the end of it as another.
