According to the documentation found at
http://developer.ebay.com/DevZone/bulk-data-exchange/CallRef/startDownloadJob.html, the procedure for encountering a "System" category error is to **"contact Developer Technical Support"**. Which would be the appropriate forum to post the question in if the system error is regarding the Large Merchant Services API? I do not see a forum for that API. Thanks in advance for directing me to the right place.
