Thanks Noel and Matt! That's just what I did and it worked! Has relieved my computer of a lot of "stuff" Now I have another problem with 2016 Ultra Pak on the Hard Drive. Often when I am trying a new style or even an old style and have selected a particular instrument a little sign will flash up saying "Part #3, instrument not found" and nothing loads and sometimes it shuts down the whole program. Has anyone else encountered this,and what did you do?
