I'm sorry about the problems with Filevelocity, it was my fault: my account is not premium so they began to delete files older than one month. Glass was mainly affected. I will reupload everything as soon as possible (Filevelocity is down this morning).
About Filefactory: they're not very fast, they often close down the downloads for free users but they're almost invincible. I never had a file deleted for DMCA or inactivity... maybe you will not be able to download it today, but sonner or later you will.
