[Unable To Install Packs]

Whenever I put any pack delivery URL in the box, it will say "Invalid Technic Platform delivery URL", even though it is the right URL. It's completely prevented me from installing any packs, I'v tried many packs and they all had the same results. In the past I was able to install packs perfectly fine so I'm very confused to why it's preventing me from installing them now.

[Can't get past black screen on custom modpack]

Install Thermal Foundation. It's required for Thermal Expansion. It is the world gen and ores and Thermal Expansion uses a lot of stuff from it.
