Upload leads - immediate error message

Upload leads - immediate error message

Hi
 
I have 160 leads in CVS format I wish to upload. I cannot even select the file.  Can you help?
 
This is what happens:
  1. I got to - Import leads > Browse
  2. It opens a file menu - Windows (C) - windows - sytem32
  3. As soon as that opens, an error message comes up - "c:\users\Arlo\desktop is not acccesible - the directory name is invalid"
  4. I tried to click through it 'ok'.  The error message disappears, the file menu stays open.  I try to go into the correct location to find my CSV file - it shows nothing, only folders, and each new area I go into - a new error box comes up (same message).
  5. Basically I cannot upload any leads and I am stuck.
 
Please can you advise?
