Update! Well it's not as sinister and scary as I thought. My fileswap premium account had a past due amount for 3 days (eye roll) so they deleted some of my inactive files, that is files that haven't been downloaded very often or not much recently. Many of my files are still there, but are few are missing, so here's that link still for those of you who need the missing pieces.
2nd Update. All of the files are now restored. I'll leave this post up in case you need them later.
