negative value

[Eudemon]

ver 2.1
after run a purge, when i go to space manager
it shows a negative value, btw i still have 2 files there

another one (if it is not too much trouble)
if i choose not to delete the entry for the file
can you make it automatically show the error message on the entry page instead of when user click it then show

tested, max_download n wait time still count for above downloads (file doesn't exist)
