John:

If it is not a database issue then it could be one of either a temp file specific to this database that did not get deleted or it could be an invalid range selection on the report filters.

Often the problem can be as simple as setting a filter from <blank> to <blank>. This means to start and stop before the first record so no records will be returned.

To eliminate the first go to the users c:\documents and settings\%userprofile%\local settings\temp folder and delete the contents.

To eliminate the second;
a. open this database
b. under the edit menu select Company Profile
c. on the system report options tab look for and deselect 'remember report settings' (about 2/3 of the way down).
d. click OK and close the database. This will reset all of the report filters back to the default.
e. reopen the database and try the report again without changing any of the filters (click on preview so that you do not eat up a ream of paper).

If the report works then re-apply any filters you were trying to use. If the report stops working again then it is your filter(s) that are a problem. Use the finder to validate any filters you are trying to use.
