Unusual "nonexistant" reports

[AUGuy]

I've got several reports that contain subreports. Yesterday while some coworkers were exporting my reports to PDF using Adobe Professional, something went amiss with a handful of reports/subreports.

I've got 3 reports/subreports that at some point during their exporting, seem to have been phantom-deleted. Meaning, on the Modified/Created portion of the detail list view next to the report it shows 12:00:00 AM. When you click one of these reports, it gives the error:

The report name 'reportname' you entered in either the property sheet or macro is misspelled or refers to a report that doesn't exist.

These are the 3 subreports to the main report. When you click the main report, it returns the error:

17 errors occurred when you loaded the form or report. You loaded a form or report that has controls or properties that Microsoft Office Access doesn't recognize and will ignore.

When you click OK, it doesn't do anything. I'm unable to open the report to design or preview or anything.

This is the first time i've seen anything like this. Being that my database utilizes many reports (80) for performance reporting for several employees, I'd like to find the root cause of this problem to make sure it doesnt happen on a larger scale and really cause some havoc.

Thanks for any help.

An additional symptom: I thought i'd try importing all of my reports into a new, clean database. I created one, went to import them via Get External Data, and only a small portion are showing. So a vast majority of the reports arent even showing on the menu to import objects.
