Whenever I try to launch Tekkit Legends the launcher starts to download an update. After downloading, the progress bar says that it's "grabbing" files and then shortly after, it freezes. sometimes the progress bar reaches about 14% or 8% but usually it just stops at 2%. When it reaches this point I can't cancel it any way other than closing the launcher, which causes it to start over again next time i try to play. I've tried leaving the launcher open after it's frozen for about 2 hours, yet it still doesn't move.
All the other modpacks i've tested download and play fine, this problem only happens with Tekkit Legends.
Image for reference and/or proof: (the problem almost always makes it freeze at 2%)
