Cant access Time Machine

Hi I was wondering if someone can help me.

Ive Had to do a clean install of Yosemite on my macbook.  I backed the computer up with time machine but selected regisered user not guest.

When ive tried to get all my files back through time machine its only going back to today when Ive just restored.  Ive checked the file size and its 430gb but if i check in time machine preferenceces its only saying 15gb.

Ive just been looking through the pdf manual and it says you must select guest.  Is this my likely problem,

how can i go about fixing it.

Best Regards any help will be greatly appreciated.
