Try 'Track - save track to file'.

Then try to open that wav file in Realband and see if you get any clues.

Were they recorded on that system?

Have you changed audio drivers?

Also try 'File-Open backup' and see if the backup file has this issue. You may be able to export them from the backup file ... and import into new file again.
