I updated the Yahoo Short Interest Tool error handler so that it will catch when the Yahoo Finance servers momentarily refuse a data connection. It will try again up to 10 times, and then will write #N/A’s to the symbol results and move on to the next symbol. This should fix that particular “This file cannot be accessed” bug that you may have been getting. However, there’s a new issue where I can’t get data for any symbol past BBBY in the S&P 500. Not sure why. GRRRRR
The newest revision is out on my Google site under Released Tools.
