multiple copies of company file in library

Hi, 

My old computer died. Bought a new one, installed old software of AccountRight Plus [12.9] but had difficulty adding the data as it was a slightly different version [13]. The solution was to upgrade to 13.5 but now I have 4 extra copies listed in My Library. When I look where MYOB is save to in my computer, the extra copies do not show.

How can I get rid of the extra copies from My Library?

Also, how do I re-name the ones that I wish to retain?

Can someone help me?
