No Destination File To Select When Importing

Hello,

I am trying to import a csv file into calendar. I go to file>Import and
Export>Import From Another Program or File>Comma Seperated Values
(Windows)>Browes to the csv file I want to import>Select Destination File:
but there are no folders to select. I don't know what to do. I have
imported
files before with no problems. Any help is appreciated.
