Simfiles with No Files???

First of all, I am a new user here. I navigate on Simfiles (both official and custom), and I am very impressed you can make your own banners, bgs and jackets for songs not on DDR yet. But something strange is happening here...
Several custom simfiles (most of them are old) have lost their files (f.ex. ZIP archives), and there is no way to find them in another website, sometimes neither in StepManiaOnline...
A good example is NemeSETUP Sims, created in 2007 and re-uploaded on StepManiaOnline (unluckily the pack's songlist starts in Digitank System)
Is it that the admin decided to delete the files of older simfiles, or is it just a bug?
In case of being the first answer, I need ZIP, RAR, etc. files of the simfile packs whose songs suffer this error. Otherwise, I guess there is a way to re-upload the affected songs' files.
I will be waiting an answer, thank you

If a file in the database has No Files uploaded, it could be because that person uploaded it as a template and then never finished the file/pack. Just a thing that happens unfortunately.

Edit: I believe this was before you could make individual files private #History
