Font issue. Project created in CS5 converted to CS6

After I open a project I created with cs5 in cs6 the fonts are changed and the position is different.

Same computer?

  I also noticed the title location on the title editor does not match the title location on the preview monitor.  It shows in the center on the title edit but is to the very far right on the preview monitor. 

Can I see what fonts were changed? 

Thanks!!
