I thinnk i have a solution for you as i had this same problem. If you are the administrator of your computer then run the launcher as administrator once in it shouldn't have the tumblr feed as being down and then click options and the build type you want. The latest one isnt working for me but im using the one before that and that works. It's not the best as it's not the latest update but it's better than nothing right? Hope this helps for you.
