Automation Script runs within Application but fails in scheduler

I am running a script in 5.6 that runs fine in the application but fails in the scheduler. The failure is "[Microsoft][ODBC Excel Driver]Invalid use of null pointer". This fails in the Import widgit on the third file I import. I have other scripts using similar files with no issue. This script has been moved to a new PC and it is the only one giving me issues. I am thinking I may just need to rebuild the script from scratch. Looking for ideas.

Hmmm... couple things come to mind.

Otherwise, if the automation script isn't too involved or lengthy, it might be best to re-define it on the new workstation. I've seen this on rare occasions where "something" gets cached/defined in the workflow file (like a non-existent ODBC driver) and the issue can be difficult to troubleshoot.
