I purchased 2 sets of soundpools from catooh.  I downloaded both of them at the same time and the are in the same folder.  They are in the same file formats.  One of the soundpools I can see and the other I cannot.  I can use them if I search in the file folder but not in the styles field.  I have even clocked the "Add" button and clicked on the file I want to add but the trouble file will not add to the list.  Please help.  I have both tuned the program off and then on again a few times and restarted the computer and it did not make a difference.
