Hi, there is an error when creating thumb image:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'thumb_image' in 'order clause' (SQL: select `kurtjensen_privatefiles_downloads`.*, (select name from `kurtjensen_privatefiles_folders` where `kurtjensen_privatefiles_downloads`.`folder_id` = `kurtjensen_privatefiles_folders`.`id`) as `folder_id`, (select concat( surname,', ',name) from `users` where `kurtjensen_privatefiles_downloads`.`user_id` = `users`.`id`) as `user_id`, (select name from `kurtjensen_passage_keys` where `kurtjensen_privatefiles_downloads`.`permission_id` = `kurtjensen_passage_keys`.`id`) as `permission_id` from `kurtjensen_privatefiles_downloads` order by `thumb_image` desc limit 20 offset 0)

Sorry, actually it happen when i click header column 'Has Thumbnail' at List Files.

I fixed it by making the column not sortable. Not going to push it out until I make some other changes. In the mean time, Don't try to sort by that column.

Thanks for reporting.
