Unfortunately about 36hours ago the Hard Drive in my web server decided to end its little spinning life. Although the site has been restored from a couple of backups some of the file download links are not working.
The files are still available but I need to fix the download links - please be patient :)
For anyone running download monitor out there, the newer update changed the DB table names. Don't do what I did or rather didn't.... and forget to change the SQL backup scripts to reflect these changes.
