I encounter an error window when clicking on the Inbox. The Inbox shows the number of emails, but the main window is empty. So far, I have tried repairing the Inbox via the Maintenance Center and compacting it, but neither helped. I also attempted to delete the TBN file inside the Inbox folder to rebuild the database, but that didn't help either. Reinstalling The Bat! also didn't solve the issue. Are there any other ways to recover the emails and fix this error?
