["Some content updates could not be downloaded from our servers. Please restart Warframe to try again.]

I had the same problem until I restarted my xbox. You have to do a full restart by holding down the power button for 10 seconds. Once you restart it, Warframe should tell you it needs an update. Run the update and try starting it up.

[Dread Texture Update?]

The dread seems to have this strange silver tint to it's accents no matter what color I put it, I think it has to do with PBR textures but I'm not sure. Will it be fixed eventually? 

[Glaive Prime Texture Update?]

Recently I've been able to customize what color the gold accents should be on some of my prime weapons and frames, I would like it if DE extended this customization option to more weapons including the Glaive Prime, which I think deserves one. Hopefully they will.
