I purchase my computer and it was already loaded with two software one came with it preloaded Microsoft Work and the other a 60 day trail period (Microsoft Office). Since Microsoft Work came with it I use it intead of Office. Now the 60 day trail period is over now either program don't work. Don't understand when I purchase the new computer it was pre installed came with no CD. Windows Vista Home Basic. What do I do to get it to work?
