Thanks deepceleron, I've got it working now, and I really appreciate your help with this!  After updating my batch file, I've been able to successfully download the historical trade that I missed.  Is there any particular address you'd like me to send some donations to (I assume the one in your signature is fine)?  Also I would like to further commend you, as this sierrachartfeed update is a significant improvement over the older version I used, and has now removed the 10-15 minute gaps of trade data between the historical data and live streaming feed which is great
