I simply could not find out why the XMLs were being deleted as soon as they were dropped in the in the CommercialsXML folder. I took a stab in the dark and assumed DTB was deleting them as part of some file cleanup.
It did not hurt too that there was a newer version out. I went to the new version and all is good. I created a scheduled task using the commscan.bat. Everything is working great. Thanks for all the help.
