Sounds like you've got some extraneous temporary files - that is what the first error message typcially means. In some previous usage, the report did not successfully clear the report files, and now the next time you use the report the required file cannot be created, or the file just created could not be deleted.

Or perhaps a file is locked on the system and the printing of the new report has an issue.

Do you get the same error(s) if you go to the Payments tab and click the Generate button? This does the same file manipulation as previewing the Pre-Check Register report.

Ensure that there are no data files that don't have full read/write access. Or missing file permissions.

The second error 'list index out of bounds (0)' typically means a drop-down field needed to be generated but was unable to, and the index for display could not be read. This likely is a symptom of the first error.
