Issues like you are having are usually associated with corruption in the data file, less often an installation issue.Running the File>File Operations>Copy routine along with Validate and Super-validate can help weed out the file corruption. Sometimes if the corruption is in the scheduled reminders table, those routines may not solve the issue. In that case, deleting all of the reminders and starting over works. Make a copy of the data file first so you can revert to it if unsuccessful.
