The Turtle Creeper

First, all of my modpacks went offline and I tried everything to get them back online. Then I deleted the entire .technic folder and redownloaded it only to find all of the modpacks (including defaults) were gone. Where they should be, the "add modpack +" icon sits. I have restarted my computer repeatedly, redownloaded over and over, and still the files are missing. Any help?
