I have imported the launcher to the latest KSP, did few upgrades, posted it on Steam Workshop. It's available at https://steamcommunity.com/sharedfiles/filedetails/?id=1466791594
Think you've got a mistake in texture packs.
duststorms.dds:
SVE_MedResTextures.zip - 11MB
SVE_HighResTextures.zip - 2.8MB
Shouldn't it be the other way around? Larger file in High res pack?
