Isn't Formularios "Forms"? The query is looking for a value from a form, but the form isn't loaded? And that's because of code that didn't run on the other pc? And that's because it's a Trusted Locations issue? Just guessing.
As for posting sensitive data, you can always copy the db, strip out records and only leave enough to create the issue (assuming any are required for this problem) and Ctrl+H (find and replace) in sensitive tables and change your boss's name to Donald Duck (or something like that). If you're db is split DO NOT delete records from the back end while maintaining the same links. You will delete from the primary tables. If it's not split, then deleting from your copy should not cause any harm.
The more we hear silence, the more we begin to think about our value in this universe.
